Adding a predefined value in Data Row

Actually I have string value in File_Number(String variable) .I was trying to insert that File_Number variable along with another string like below

{“FileName”,File_Name.ToString)

But, I am getting the error which was in screenshot. @ovi @vvaidya @badita

I think there’s a typo. You typed {“marees”,.File_Name} instead of {“marees”,File_Name} with an extra ‘.’ before ‘F’?

No I have given as you gave.But When I am trying to select from expression editor,after selecting the File_Number, .(Dot )coming automatically. And I am getting the error which was mentioned above

You can get that dropdown window as well with ctrl + space. No need for the “.”

You should validate the scope of the variable.
