Input mask to add prefix?

User TheFencepedia 2025-09-25 18:20:40

Hi there,

I want to automatically add the prefix Q to an alphanumeric added in a form field. However, it does not have to be a money, a phone number etc.

I just need it to be Q0001 or whatever it is that they enter.

How do I do that? When I click the "More Information" button on that field, it does nothing, so I thought I would ask directly.

Thanks.

Hi,
right, the link for the additional info is no longer working, it'll be fixed for next release, thanks for pointing that out. For your case, the configuration you need is:
- Input Mask: Select predefined or enter custom mask - > AAAAAAA (enter as many 'As' as characters you want to allow)
- Mask prefix : Q

Hope this helps, regards
