Issue with accessing custom variable across questionnaires

Question

I would like to give my participants a keyword which depends on the group that they are in.

In the first questionnaire, I assign participants to a group via randomizer and save the group assignment into a custom variable called group using the registerVariable() function. In the second quesionnaire I want to present the keyword which is a text in variables RG02 or RG03. The code is

if (value('group') == 1) {
    text('RG02');
} else {
    text('RG03');
}

Thetwo questionnaires that are connected via a serial mail.

However, when trying to access the variable group in the second questionnaire in the debug modus, the text of RG02 shows but I also receive the following error message:

"The variable groupe does not exist in this project (see variable overview). Therefore, no response value can be retrieved."

Has anybody a solution for this or maybe an easier way to solve my issue with the keyword?

Thank you very much for your support!

Okay, then you'll have to use the database to transfer the information from case A to case B. Please follow this manual: Exchange Data Between Two Questionnaires
