Dear colleagues,

Is there a possible solution to avoid the error message
"Error in IF expression; Cannot apply opGT to missing operands"
during data entry under the check commands below?
NB: (values and labels 0=No; 1=Yes) for varsv1

varsv1
  COMMENT LEGAL USE label_varsv1
  MUSTENTER
  TYPE COMMENT
  AFTER ENTRY
    IF varsv1=1 THEN
      GOTO WRITE
    ENDIF
    IF varsv1=0 THEN
      RELATE idno file2.rec
    ENDIF
  END
END
I am not sure if this error message is related to a bug or typo.
Your help would be very appreciated.
