Hello,
That’s excellent that you’ve fixed it.
While you using Make functions you’ve to follow proper syntax and data type as well.
{{replace("hello-world-with-dashes"; "-"; space)}}
You can also use SPACE instead of " ".
Don’t worry just copy my formula it will automatically work as per make’s function syntax.
After copy/paste, Just change the string to your variable.
P.S.: Always search first, Check Make Academy. If this is helpful, mark it as a solution
