Hi team,

I'm currently scripting a survey where I need to ask two numeric question Q037 and Q038.

The first question (Q037) is asking what is the highest acceptable price that someone would pay for a coffee machine.

The second question (Q038) is asking what is the lowest price.

I have scripted the questions and I have applied a Question validation equation: sum(self.NAOK) < sum(that.Q037.NAOK) to question (Q038) to make sure that in the second question the respondent would not enter answer higher than the one in the first question.

In addition I have added in the question text the following expression:

{if(sum(self.NAOK) > sum(that.Q037.NAOK),"Please correct your answer. Your answer should not exceed {Q037}.","")}

The issue is that no matter what I have tried the value from question Q037 is not shown (marked in Orange). I believe that this is due to the fact that {} are used twice.

Could you please advise how to proceed in order to show the value from question Q037 in the question text?

P.S. I'm using Limesurvey v. 2.73

I believe that this is due to the fact that {} are used twice.

You are right.
You should do it like this.
{if(sum(self.NAOK) > sum(that.Q037.NAOK),"Please correct your answer. Your answer should not exceed "+Q037+".","")}

But a better way would be to set the maximum value of Q038 to Q037 (Advanced settings).

and the error
