RDLC Display TextBox within Body on Last Page Only

Hi,

I have a table with a group footer.  In the footer i have a textbox.  I only want to display this on the last page.

I tried =IIF(Globals!PageNumber=Globals!TotalPages, False, True).  The problem is it doesn't let me use this within the body, only in the header or footer.

Is there anyway, i can display this textbox only on the last page?

Thanks in advance
