Hi all,
I try to check if two fields in a form have values or not. But my logic doesn't work. May you have some idea what's wrong?
CODE:
<container [...]>
<leave>
<check expr="@Offer_Category == null and @PDF_Link == null">
<error>Please check that PDF_Link or Offer Category are not empty.</error>
</check>
</leave>
</container>
Many Thanks and best regards
Robert
