Welcome to the Make community!
There is no parseInt function in Make. If you want to use JavaScript, see [Free App] My Toolbox of Useful Modules
Otherwise, you can select the built-in function parseNumber from the variables panel — “Parses a string with a number and returns the number.”
{{ parseNumber(number; decimal separator) }}
For more information, the function’s documentation can be found in the Help Centre. You should also complete the tutorials in the Make Academy.
Hope this helps! Let me know if there are any further questions or issues.
