Multiple forms submission / Cascaded forms

[bleep99]

I'm trying to make several forms on a page. I would like someway to submit all of them... I'm using a normal submit button but that only submits the last form:

<input type="submit" value="Generate" />

Is there any way to ensure that either
i) All forms are submitted by one button
ii) OR is there a way to have forms embedded inside other forms?

Thanks

forms cannot be nested. just make all of your fields in one single form.

why would you need to use more than one form?

I was trying to update parts of the page at a time.... so I was trying to use onchange() to several form elements and wanted each element to only update a portion of the page. But I've worked it now to refresh the entire page.
