hi, i am new to crystal and i am basically training and learning as i go. i am working on a report that displays patient number and date of last diagnoses.
I have multiple diagnoses fields however not all are answered. When not answered crystal outputs "unknown"
I would like to supress this field if there is no data entered in the system. Or instead of displaying "unknown" i want it to say "No Diagnoses"
I know the start of the formula is "if isnull"
I tried formatting the field in the supress area for the formula i entered the following
if isnull ({history_diagnosis.axis_I_diag_value_1}) then 'No Diagnosis'
however it get the message "formula result must be boolean"
