Help with JS "check all/ uncheck all" box

[virtualcreative]

New here and not a JS wizard (at all). I need to get two little buttons working for check all/uncheck all on a form list. When I isolate the script on this page:
http://www.hotelfandb.com/subscribe/hot-leads-test.htm
the buttons work.

When call this form from another page it does not, even when I put the script in the head file (topnew-copy.asp)
Here's the one those same buttons won't work on:
http://www.hotelfandb.com/subscribe/...yfree-test.asp

Does anyone have any ideas why, and how to get around it?

Help is much appreciated!

Use a validator to fix your HTML.

You can't just drop a whole HTML page, including doctype and all, right into the middle of another HTML page and expect it to work.

Unfortunately its not up to me - I didn't design the page, just being asked to make the check box work. The hot leads file it is calling in is in several pages. Should it be an asp file instead? (basically, what can I do to get the javascript to work?)

Basically, you're nesting two forms, which is not allowed, so the browser won't see the inner form, which you are trying to access using Javascript. What you could do is access those checkboxes as elements of the outer form instead. I won't go into more detail, though, since this is not the right way to fix this. Validating the HTML is.
