I use LimeSurvey in a small call center. Many times I'll have a question that requires numeric input, such as the respondent's age. I like to have it set so that the interviewer can only enter numbers between 18 and 100. The problem is I also need them to be able to enter an 'X' for refused (which happens often). So, I need to be able to restrict them to either entering a number between 18 and 100 or the letter X. So far I've been unable to accomplish this using validation. Any help would be greatly appreciated and I apologize in advance if I published in the wrong area.

Thanks,

Andrew

You can use a short text question and use a regular expression for validating the inout: docs.limesurvey.org/Using+regular+expres...tions+for+LimeSurvey

Try this regex in the "Validation" field:
