Create another field (FIELD1) always hidden and edited with this formula in TRANSLATE:

@Abstract( [DROPVOWELS]:[ABBREV]; 12; “”; “YOURRICHTEXTFIELD” )

The first parameter is not imporante. It returns you rich text field converted to text with the max length you want (12 for this case).

In the validation, set this formula:

@if( @trim( field1) = “”; @failure(“The field text rich cant be empty!”); @success)
