How can i make that a subform does not overflow on an other one?

Hi gents,

My question is pretty simple yet it gives me a lot of troubles.

I have a page, containing a header and a footer in the master page. In the middle of this page, i have a table that overflows on the next pages because it is too big to fit on one page, and below this i have a subform containing a legend for the fields in the table. My problem is that y table always overflows on my legend. Here is a simplistic drawing to explain my problem :

My problem here is that the red square(the table) goes over the green square(legend). How can i prevent this?

Thanks alot for any input!!
