Welcome to the Make community!
You have the parameters mixed up.
To do this, you can use the built-in function:
- formatNumber
formatNumber(number; numDecimals; [decimalSeparator]; [thousandsSeparator])
This function may have also been covered in the Make Academy tutorials — refer to the Make Academy Course Overview to learn more.
Here’s an example of how you can use this function:
{{ formatNumber(150000; 2; "."; ",") }}or
{{ formatNumber(1.cost; 2; "."; ",") }}
(copy-paste the above into the field, or type it exactly as shown)
Hope this helps! If you are still having trouble, please provide more details.

P.S.: investing some effort into the tutorials in the Make Academy will save you lots of time and frustration using Make!
