Hi,

I would like to create the following validation criteria for "Short free text" question: first sign must be capital letter A-Z and second sign must be number 0-9, everything else can be numbers. Is it possible to do this from the menu "Edit question -> Advanced settings -> Question validation equation"?

I tried some of the examples equations that are mentioned in the limesurvey manual but for some reason I could not get them to work (even when I just copypasted them). I would really appreciate if you would be able to tell me what I need to type in the "Question validation equation" box to get the rule working. Thank you in advance!

Hello,

try this:

/^[A-Z][0-9]/

Thank you for the syntax! Unfortunately, it seems that I still have trouble getting the code to work properly. Here is a screenshot of the logic file.

Okay,

I'm using built 2.63 and there it ooks like this:



Which version do you use? Obviously the regex isn't recognized.
Maybe this works:
regexMatch("/^[A-Z][0-9]/")

Wait, I just see, that you inserted it in the Question-validation equation.
You have to insert it here:

Thanks for the quick reply. It's working now! I was typing the equation into a wrong field like you said

You can use either the "Validation" or the "Question validation equation" fields. The "Question validation equation" allows for far greater flexibility in the validation criteria but requires the use of Expression Manager syntax.

Something like this (which also restricts any characters after the first two to be numeric):
