Need help with Marketo Form to prevent multiple re-entry of company name

[Tentenation]

I'm new in forms and would like to figure out if there is a way to hide the company name field if it has already been filled out before? Will also need to add a button that company name can be change incase the registrant want to update it. Is this possible?

Easiest way to do this is include Company in the Progressive Profiling block. It won’t be shown in if it’s filled.

Then your “Change Company” button replaces the default form with another form where Company isn’t in the ProgPro block, i.e. is always shown.
