Master page content area height

Hello

I have a subform within a master page content area,

The subform has table which i allowed the content to break to the next page.

When i try to get the height of the subform it only gives me the height from the first page and ignores the rest on other pages the table broke to.

I need the height of the subsequent pages in order to position another subform at the bottom of the last page.

Your assistance will be greatly appreciated.

Thanks in advance
