Menu
I have a form which I am trying to have dynamically update and seems to be
running into a brick wall on why the form will not update the “Choose
Product” dropdown. For whatever reason, the JavaScript inside the header
of the page are not communicating these values down to the aforementioned
drop (select) box.
*Note: I did not originally create this code and find myself trying to
absorb something maybe a little above my head.
**Note: As stated in the thread subject, I am a complete JavaScript newb so please go easy on me. I wish to learn and learn it well, not to get trashed by those whose knowledge is far greater than mine. In short, any helpful pointers would be most appreciated.

Here are the relevant HTML form fields in the body of the page

<form name=”myform” method=”POST” action=”fulfillment.asp”>
<fieldset class=”corporate_field”>
<div class=”corporate_signup”>
<table ID=”Table1″>
<tr>
<td>Fulfillment: </td>
<td><select id=”fulfill” name=”fulfill”
onChange=”changeAction(this.value); SelectSubCat(this.value);”>
<option value=””>–Select your fulfillment option–</option>

</fieldset>
</form>
I’m reasonably certain that there is something missing from the HTML form
field (Choose Product) that will pull in the variable set by the
SelectSubCat(url) function, I just don’t know JavaScript well enough for
this to be completely obvious to me.
Any help would be greatly appreciate. I can send the entire page if that
would be considered useful.
Thanks in advance,
