Submiting two forms with one button

Is there a way to submit the data in two forms when the submit button is hit in one form? Example: the info in form a is always submited when the submit button in form b or c is pressed.

Thanks

<form name="a">
...
</form>

<form name="b">
...
<input type="submit" onclick="document.forms['a'].submit();return true;">
...
</form>

This should do it.

I tried the code, but when I tested it, it was still only sending me the info from the form which contained the submit button. Any idea what I could have done wrong or what I might have misconfiged.

To help you further I would need to see at least the relevant parts of your code.
