Visibility Expression Hide if textbox of tablix 1 is equal to textbox of tablix 2?

I am attempting to write a row visibility expression that will hide the row if text box 1 of tablix 1 is equal to textbox 1 of tablix 2. 

I am getting an error.  Is it my expression or is this just not possible.  My expression is:

=IIF(Fields!Name.Value=(Fields!Name.Value,"Tablix2")True,False)

Thanks in advance!
