Thanks in advance


Is “saveapp” a multiple action button?  Are you using the Action Framework to save your changes or perhaps a snippet?

Most components allow marking a field “required”.  The field will be highlighted in red (by default).

Search the community or tutorials.  There are lots of good examples.

Review your models and ensure required fields are marked as required.
