do not put spaces in the form element names (name=Butternut_Squash_Soup)
is good.
in the <form ..> tag add something like onSubmit=validate_form() like
<form name=f1 method=post action="your_url" onSubmit=" return
validate_f1(this);">
....
</form>
now somewhere in the <head> part put something like
<script language="javascript">
function validate_f1(f) {
if ( !f.Butternut_Squash_Soup.selected)
f.Butternut_Squash_Soup_Quantity.value='';
}
put other form elements that u want to check in this function.
(NOTE this is untested. check a javascript book to get correct syntax)
