Need some javascript then … don't have time, maybe tparner have more idea : www.limesurvey.org/manual/Workarounds:_M...ime_using_Javascript

Else, maybe you can try with www.limesurvey.org/fr/?option=com_sobipr...textadapt&Itemid=729 and an updated version of unique ? something like unique(self.sq_choice,self.sq_other).

thank you very much

arraytextadap ：it is very good Extensions ,i have already use it .

Question validation equation : unique(self) and count(self)==max(self)

when i write this equation in the question, then the question display.

?
1: I say in Question validation equation : it's not for display or not the question …
2: I think you can use unique with sq_ to get the unique by column for the 1st column (the sq_choice if the first column is named choice).

when i try like this ：

set a array question Q1 with dropdown

y1 y2 y3 y4 y5

x1

x2

x3

i want the answer of x1 ,x2 ,x3 must be different . i find the example from your web ,and it said :unique(self)

i try Question validation equation like this :

unique(Q1_x1,Q1_x2,Q1_x3)

and i find the question Q1 will been not display ,and it was hided...

?????? Where did you put this equation ?

Else there are an error : Q1_x1 etc … didn't exist : you need to use
unique(Q1_x1_y1.NAOK,Q1_x3_y1.NAOK,Q1_x3_y1.NAOK).

See www.limesurvey.org/manual/Expression_Man...code_Variable_Naming / Array (Multi Flexi) part.

i set Question validation equation :

unique(unique_x1.NAOK, unique_x2.NAOK, unique_x3.NAOK)

but it dose not work.
