Hello,

I can't understand why this would not work.

<script blah blah>

</script>

it errors saying null or not an object. ??

the only way i got this to work was to include
"var mainForm = document.search" in every function

thanks

Without seeing the rest of the code I will have to assume
1)The code is in the HEAD section of your html.
2)You have a Form named "search"

If this is the case then "document.search" does not exist until the BODY of the document is parsed.

Try
<BODY onLoad="var mainForm = document.search;">

wouldn't it be better...

<body>
<script>var mainForm = document.search</script>

then the function can already run even if there's a big image in the page still downloading?

Yes the script is in the head and I do have a form called search.

What your saying makes since in why it does not work.

Thanks

Try placing the script after the form

<body>
<form name="search">
</form>
<script>var mainForm = document.search</script>
</body>
