Number Thousands separator

Hello,

I’m trying to create a form with number fields in currency format: I made some number fields and converted them to display them as currency with before-after imputs.

I would like to display them with thousands separator rounded with a decimal value of 0 but by no means will it succeed. If I try to write it to the shortcode found in knowledgebase nothing happens but I do not know if I’m trying in the right place its a bit unclear to me.

Is there any way to do this to display the number separated by thousands? How can I solve this?

Thank you!
Peter
