Dear LS Team,

I have 2 questionn:


Q1. When you buy your new House? [ANSWER IS CHOOSE MONTH AND YEAR]

ANSWER: 2013 OF JUNE [DATE FORMAT]

Q2. When you move to your new house? [ANSWER IS MONTH AND YEAR]
[valid answer in Q2 cannot less than Answer in Q1, so if responden choose date less of 2013 of June will rise alert message]

How to make date validation like question above in lime survey?


Need help

Thanks & Regards,

JajaS

Assuming the first question code is "date1", this seems to work as the question validation equation for a normal date question:
this >= date1



.

What question type are you using for this validation equation? I don't see a Question validation equation for the Date/Time question type
