Online Order Form?

[hans_cellc]

I have been playing with two options but just dont seem to get the coding right. Can someone please assist. Using ie9 but same problem with all browsers.

first snippets.
HTML:

Code:

<!-- Row 3, Col 3 purchase boxes -->
<td colspan="1" height="120" align="left">
<input style="margin-left: 60px" type="text" name="bed_359" size="3" maxlength="3" onchange="calculateValue(this.form)" /> R359</td></tr>
 
<!-- Row 10, Col 2 Order Value Box-->
<td colspan="1" align="left"><input style="margin-left: 60px" type="text" name="total" size="10" 
onfocus="this.form.elements[0].focus()" />
</td></tr>

javaScript:

Code:

// Function to calculate order value 
function calculateValue(orders) {
var orderValue = 0;
var value = 0;
var itemPrice = 0;
var itemQuantity = 0;
 
// Run through all the product fields
for(var i = 0; i < orders.elements.length; ++i) {
 
// Get the current field
formField = orders.elements[i];
 
// Get the fields name
formName = formField.name;
 
// Items price extracted from name
itemPrice = parseFloat(formName.substring(formName.lastIndexOf("_") + 1));
 
// Get the Quantity
itemQuantity = parseInt(formField.value);
 
// Update the OrderValue
if(itemQuantity >= 0) {
value = itemQuantity * itemPrice;
orderValue += value;
}
}
 
// Display the total
orders.total.value = orderValue;
}

Second code:

Code:

<!-- Row 9, Col 3 purchase boxes -->
<td colspan="1" height="120" align="left"> 
<select style="margin-left: 60px" name="shirt" value="215" onchange="calculateValue(this.form)" />
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option></select> R215</td></tr>

Java

Code:

// Function to calculate order value    
function calculateValue(orders) {
    var orderValue = 0;
    var value = 0;
    var itemPrice = 0;
    var itemQuantity = 0;
 
    // Run through all the product fields
    for(var i = 0; i < orders.elements.length; ++i) {
 
    // Get the current field
    formField = orders.elements[i];
 
    // Get the fields name
    formValue = formField;
 
    // Items price extracted from name
    itemPrice = formField;
 
    // Get the Quantity
    itemQuantity = formField.selectedIndex;
 
    // Update the OrderValue
    if(itemQuantity > 0) {
    orderValue += itemQuantity * itemPrice
    }
    }
 
    // Display the total
    orders.total.value = orderValue.toLocaleString();
}

Please help its probably something simple.
