prevent the form from clearing fields

Hi,

I need to do some functions after the form has submitted based on choices the user made. I can’t do this because the form immediately clears on successful submit.

There use to be a simple way of preventing this in the scripts.js file, but the code is no longer the same and it’s no longer a matter of commenting one line of code.

Is there any other way to prevent this behaviour?

Thanks,
