Data validation in the field

Question

Hi, we use a Survey123 form for soil tracking on construction sites. Our most critical info is the truck licence plate. Since we allow field workers to copy an existing record as a new record, is there a way to check that the licence plate question was updated in the copied record ? Thanks

Thanks Doug, I will try something and let you know!

You could add that check to the relevant somehow.  That is how I "blanked out" fields in the past.  The hard part is there is no way to "keep value" since that would be a dependency loop.

Now I am thinking

Have a field with a calc of once(now())

Then have a field calc on a question Enter new plate Yes/No and calc the yes or no based on above

Then have your license field relevant on the Yes/No

That is all I can think of.

Just tested. A copy wont change the Start, but it will change the End. so how would it be set? Would you set that condition in the Default column? if not(now() = End) then licence= ?. I know my syntax is wrong...
