Welcome to the Make community!
These are invalid:
Your brackets, operators, functions, or special variables were not selected from the Variables Panel.
Try selecting it again from the Variables Panel, or type curly brackets like these {{ }} so that it ends up with a background color:
{{ ( }}
{{ / }}
{{ + }}
{{ = }}
etc.
I also suggest doing this Make Academy, as it covers selecting brackets, operators, functions, or special variables from the Variables Panel.
For more information, see:

- Formulas not evaluating in modules (Set Variable, Sheets) - Output is literal formula string - #2 by samliew
Hope this helps! Let me know if there are any further questions or issues. P.S.: investing some effort into the tutorials in the Make Academy will save you lots of time and frustration using Make!
