Can I validate based on the previous answer? 3 years 6 months ago #93589

luayessa Offline Junior Lime Posts: 22 Thank you received: 1 Karma: 0	I want to be validate the answer based on the answer of previous question. For example: Q1: How old are you? Q2: How old are your son? Now, the answer of Q2 should be lower than the answer of Q1. How can I do this validation?

To test, in a numeric question type, if Q1 < Q2, use it directly in advanced setting/Question validation equation

You can use regular expression to with EM in "Question validation equation" : RegExp(blabla)

Not validation equation but "Question validation equation"
See docs.limesurvey.org/Expression+Manager#Validation and docs.limesurvey.org/Advanced+question+settings#em_validation_q
