I am trying to concatenate 3 columns in a textbox in SSRS and get the following error:
The Value expression for the textbox Name uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one data set. Below is the expression I am using for the textbox.
What am I doing wrong?
=First(Fields!First_Name.Value, "Driver") &" "& First(Fields!Middle_Name.Value, "Driver")&" "& First(Fields!Last_Name.Value, "Driver")
