There is one question ask the respondent to fill his/her email. Followed with another question ask the respondent to re-type his/her email.

How to check whether the answer to those two questions are the same?

Thanks.

question one: firstemail
question two: secondemail, in this question I set question validation equation to 'secondemail=firstemail', set question valiation tip to '{if(secondemail!=firstemail,'not the same','')}'


But when I begin to input email in question one, questin two begin to display 'not the same'. Is it possible that after I input email in question two, the system begin to validation?

Many many thanks.

secondemail==firstemail : 2 = : see manual.limesurvey.org/Expression_Manager...t_Operator_.28.3D.29

Code:

{if(secondemail!=firstemail and !is_empty(secondemail),'not the same','')}'
