Reset form issues

So I had a form with id f_update_contact, and in order to keep things consistent I decided to change it to f_edit_contact.

Since it is reset by a few different button clicks and I couldn’t remember quite how many and where they were, I changed the name using search and replace in the code, and found one of the buttons which is supposed to reset the form wasn’t doing the reset any more. I know it was working previously, I had used it 2 minutes before.

So I’ve re-created the on-click event for the button and re-selected the form reset, but resetting the form just won’t work any more…

… I’ve changed the name back to f_update_contact, and it still won’t reset after selecting the action using the menus…

… But other actions I put on-click on the button work fine…

Can anyone help me understand what could be going on?

Thanks,
Antony.
