Hello,

it is called "Question validation equation" and you can see/change it if you click "Show advanced settings".

It would be nice if you could explain the EM related things in a more understandable way. I may understand what you are talking about because I actively work with it but users not familiar with EM might have problems understanding things like "you could set the em_validation_q equation".

Hi,
i'm newbiee and a i'm in a similar situation, tried to explain:

after the first login page wich is the token field
i want to ask for a second secure question which is the passport ID 9 characters (TOKEN:ATTRIBUTE_1)

i 've tried two diferents solutions:

1.- Conditions: is two make two more questions groups after the passport question, one group says: your response to Passport ID is no good, and the other group is the really questions i wat to make. I've donned it with "conditions". Like: show this question IF token:attribute_1=... But the problems is when the passport ID is wrong and jumps the group question saying "wrong answer", i don't know how to let the user come back for reentry the passport ID

2.- Question validation equation: i put regexMatch(implode('',TOKEN:ATTRIBUTE_1),this) in advanced settings wich seems to work because until 8 character the background of the field is red and in the 8 and 9 character it becomes white. But when i summit "Next" it doesn't work..

any help please? i've tryed a lot of combinations and readed the manuals "Advanced question settings" and "Using regular expressions" a lot of times and didn't get with the solutions

Help in advanced
