    Syntax errors can't get form to update mysql record

    ok so I have a "test" form that I'm working with trying to update a record in MySQL (I'm fully aware of the sql injections possibilities with this form) so here is my code:

    	// database connection //
    	include 'db_connect.php';
    	include 'data/var/variables.php';
    	//Writes the information to the database
    		mysql_query("UPDATE tickets SET 	work_performed = $work_performed,
    										 	item_qty1 = $item_qty1,
    										 	item_qty2 = $item_qty2,
    										 	item_qty3 = $item_qty3,
    										 	item_qty4 = $item_qty4,
    											item_qty5 = $item_qty5,
    											manuf_1 = $manuf_1, 
    										 	manuf_2 = $manuf_2,	 
    											manuf_3 = $manuf_3, 
    										 	manuf_4 = $manuf_4,
    										 	manuf_5 = $manuf_5,
    										 	part_number1 = $part_number1,
    										 	part_number2 = $part_number2,
    										 	part_number3 = $part_number3,
    										 	part_number4 = $part_number4,
    										 	part_number5 = $part_number5,
    										 	part_description1 = $part_description1, 
    		 									part_description2 = $part_description2, 
    		 									part_description3 = $part_description3, 
    											part_description4 = $part_description4,
    		 									part_description5 = $part_description5, 
    		 									part_price1 = $part_price1, 
    		 									part_price2 = $part_price2, 
    		 									part_price3 = $part_price3, 
    		 									part_price4 = $part_price4, 
    		 									part_price5 = $part_price5,
    		 									price_extension1 = $price_extension1, 
    		 									price_extension2 = $price_extension2, 
    		 									price_extension3 = $price_extension3, 
    		 									price_extension4 = $price_extension4, 
    		 									price_extension5 = $price_extension5, 
    		 									material_total = $material_total, 
    		 									sales_tax = $sales_tax, 
    		 									shipping_cost = $shipping_cost, 
    		 									work_date1 = $work_date1,
    		 									work_date2 = $work_date2, 	
    											work_date3 = $work_date3, 
    		 									work_date4 = $work_date4, 
    		 									work_date5 = $work_date5, 
    		 									tech_name1 = $tech_name1, 
    		 									tech_name2 = $tech_name2, 
    		 									tech_name3 = $tech_name3, 
    		 									tech_name4 = $tech_name4, 
    		 									tech_name5 = $tech_name5, 
    											cost_code1 = $cost_code1, 
    		 									cost_code2 = $cost_code2, 
    		 									cost_code3 = $cost_code3, 
    		 									cost_code4 = $cost_code4, 
    		 									cost_code5 = $cost_code5, 
    		 									pay_rate1 = $pay_rate1, 
    		 									pay_rate2 = $pay_rate2, 
    		 									pay_rate3 = $pay_rate3, 
    		 									pay_rate4 = $pay_rate4,
    		 									pay_rate5 = $pay_rate5, 
    		 									total_hours1 = $total_hours1, 
    		 									total_hours2 = $total_hours2, 
    		 									total_hours3 = $total_hours3, 
    		 									total_hours4 = $total_hours4, 
    		 									total_hours5 = $total_hours5, 
    		 									hours_subtotal1 = $hours_subtotal1, 
    		 									hours_subtotal2 = $hours_subtotal2, 
    		 									hours_subtotal3 = $hours_subtotal3, 
    		 									hours_subtotal4 = $hours_subtotal4, 
    		 									hours_subtotal5 = $hours_subtotal5, 
    		 									total_hours = $total_hours, 
    		 									material_total = $material_total, 
    		 									labor_cost = $labor_cost, 
    		 									grand_total = $grand_total	WHERE `id` = '$id'"); 
    	echo mysql_error();
    I started this out with apostrophe's around my values then was told I needed back ticks then was told I don't need anything around them at all. Frankly I just want the code to work, I ran a small test script using this code:

    include 'db_connect.php';
     mysql_query("UPDATE `test` SET      `city` = '$city', `state` = '$state', `zip` = '$zip' WHERE `id` = '$id'");
    and it works fine but when I apply the above code to the code posted above this code all I get is an error stating

    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' item_qty1 = , item_qty2 = , item_qty3 = ' at line 1

    I did get the form to work 1 time but it required me to put a value in every field which I don't want to do but after that one time it hasn't worked since.

    updated code

    so I've played around with it some more and minimized my values down to single values, no duplicates such as part_number1, part_number2, part_number3 and so on and here is the code I'm testing with now,

    mysql_query("UPDATE `tickets` SET 	`work_performed` = '$work_performed',
    										 	`item_qty1` = '$item_qty1',
    										 	`manuf_1` = '$manuf_1', 
    										 	`part_number1` = '$part_number1',
    										 	`part_description1` = '$part_description1', 
    		 									`part_price1` = '$part_price1', 
    		 									`price_extension1` = '$price_extension1', 
    		 									`material_total` = '$material_total', 
    		 									`sales_tax` = '$sales_tax', 
    		 									`shipping_cost` = '$shipping_cost', 
    		 									`work_date1` = '$work_date1',
    		 									`tech_name1` = '$tech_name1', 
    		 									`cost_code1` = '$cost_code1', 
    		 									`pay_rate1` = '$pay_rate1', 
    		 									`total_hours1` = '$total_hours1', 
    		 									`hours_subtotal1` = '$hours_subtotal1', 
    		 									`total_hours` = '$total_hours', 
    		 									`material_total` = '$material_total', 
    		 									`labor_cost` = '$labor_cost', 
    		 									`grand_total` = '$grand_total'	WHERE `id` = '$id'");
    This version of code actually works but as soon as I add a second value such as item_qty2, part_number2 the code displays a syntax error. Any suggestions?
