I created a very simple html page containing only the form
information, and a function called Test() which contained the
javascript alerting the value of custHidden. The test function was
executed upon clicking a link in the HTML. This behaved as one would
expect, displaying [object] in the alert. Are you executing the
javascript *after* the page has loaded? If the javascript is inline,
then the field will not necessarily exist at runtime.

I'm trying to do it using the onLoad() handler. So the element should
be there!

When I check this in NS6.2 - I DO NOT get an error on that. If I
enter:

document.forms["cartadd"].elements["cust"]

into the JS console for evaluation, I get this error:

"Error: document.forms.cartadd has no properties"

I can get this using getElementById() and it will work, but that
screws me for some browsers..any ideas? Here is the full form:

----------------------
<td class="line">
<form name="cartadd" method="POST" action="/preCart.php"
style="display: inline; height: auto;" onsubmit="track(this)">
<input type="hidden" name="cust" value="">
<input type='hidden' name='uid' value="<?=$uid?>">
<input type='hidden' name='smode' value="add">
<input type="hidden" name="product_no" value="<?=$pid?>">
<input type='hidden' name='start' value="1">
<input type='hidden' name='total' value="25">
<input type='hidden' name='searchpath' value="d10a8f84f260c8d20fc1">
<input type='hidden' name='search'
value="&category=Besamim+%28Spice%29+Containers">
<span class="add">Quantity&nbsp;</span><input type="text" name="qty"
value="1" size="3" class="add" /><br /><input type="submit"
value="Add To Shopping Cart" class="add" /></form></td>
