<form id="form_142745" class="appnitro"  method="post" action="">
					<div class="form_description">
			<h2>Contact Us</h2>
			<p>Feel free to contact us about anything.</p>
		</div>						
			<ul >
			
					<li id="li_1" >
		<label class="description" for="element_1">Name </label>
		<span>
			<input id="element_1_1" name= "element_1_1" class="element text" maxlength="255" size="8" value=""/>
			<label>First</label>
		</span>
		<span>
			<input id="element_1_2" name= "element_1_2" class="element text" maxlength="255" size="14" value=""/>
			<label>Last</label>
		</span> 
		</li>		<li id="li_2" >
		<label class="description" for="element_2">Date </label>
		<span>
			<input id="element_2_1" name="element_2_1" class="element text" size="2" maxlength="2" value="" type="text"> /
			<label for="element_2_1">MM</label>
		</span>
		<span>

			<label for="element_2_2">DD</label>
		</span>
		<span>
	 		<input id="element_2_3" name="element_2_3" class="element text" size="4" maxlength="4" value="" type="text">
			<label for="element_2_3">YYYY</label>
		</span>
	
		<span id="calendar_2">
			<img id="cal_img_2" class="datepicker" src="calendar.gif" alt="Pick a date.">	
		</span>
		<script type="text/javascript">
			Calendar.setup({
			inputField	 : "element_2_3",
			baseField    : "element_2",
			displayArea  : "calendar_2",
			button		 : "cal_img_2",
			ifFormat	 : "%B %e, %Y",
			onSelect	 : selectDate
			});
		</script>
		 
		</li>		<li id="li_6" >
		<label class="description" for="element_6">Checkboxes </label>
		<span>
			<input id="element_6_1" name="element_6_1" class="element checkbox" type="checkbox" value="1" />
<label class="choice" for="element_6_1">Male</label>
<input id="element_6_2" name="element_6_2" class="element checkbox" type="checkbox" value="1" />
<label class="choice" for="element_6_2">Female</label>

		</span> 
		</li>		<li id="li_3" >
		<label class="description" for="element_3">Paragraph </label>
		<div>
			<textarea id="element_3" name="element_3" class="element textarea medium"></textarea> 
		</div> 
		</li>		<li id="li_4" >
		<label class="description" for="element_4">Email </label>
		<div>
			<input id="element_4" name="element_4" class="element text medium" type="text" maxlength="255" value=""/> 
		</div> 
		</li>		<li class="section_break">
			<h3>&nbsp;</h3>
			<p></p>
		</li>
			
					<li class="buttons">
			    <input type="hidden" name="form_id" value="142745" />
			    
				<input id="saveForm" class="button_text" type="submit" name="submit" value="Submit" />
		</li>
			</ul>
		</form>
        
 
</div>

I have seen many tutorials, they all seem different. Although i cant get any one of them to work.
I set things up and nothing happens.
Can someone please point me to the right direction.
Thnx

I see no validation code. Without a code and without a validation rule it is impossible for you to receive a solution from anyone.
