Re: Form Validation-Alert box

U are not calling your function anywhere in the html

My suggestion would be to change the submit button to a normal button and use the onclick to call teh function like this:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
<input type="button" value="Submit" name="Submit" onclick="validateForm()">
<input type="button" value="Submit" name="Submit" onclick="validateForm()">

I dont see the need to pass the contact variable in to the function i dont see it being used any where

Another thing u have to swop your comparisons around like this:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
if(document.forms.contact.shipfirst.value == "") 
{
alert("Please enter your full name.");
return false;
}
if(document.forms.contact.shipfirst.value == "") 
{
alert("Please enter your full name.");
return false;
}
