Answer 1

Your question is rather vague, but I'll take a crack at the problem. Let's say that you have a textbox in the tablix column called Textbox5. In a footer row (either a group footer or the tablix footer), you can use an expression like this:

=Sum(ReportItems!Textbox5.Value)

That will sum up the values in that textbox after the functions have been resolved in each row.

Answer 2

And aggregate function can be used only on report items place in Header or Footer !!!!
