Enabling condition not working

Good morning,
I have a roster with questions on negative events. If the respondent doesn’t know of a second negative event for example, the interviewer should enter -99. If this is the case, the respondent shouldn’t be asked if they know of a third negative event, etc.
I’ve entered the enabling condition as variablename!="-99" but the enabling condition isn’t active when we test it…
Am I missing something?
Thanks a lot
Tiffany

Please specify what type of question you are using. Only if it is a text question you should use “” quotes around the value. Otherwise, use the expression without quotes as variablename != -99

Tijan, you are doing it wrong. Go back to the drawing board and rethink your questionnaire. Never rely on interviewers entering -99. This is exactly what we are trying to get rid of in the CAPI world.

Use a list question first to trigger a roster.

Best, Sergiy
