PHP code, warning!

Question

dear all,

I am trying to use a PHP code for the question "X".
even though the question "X" is successfully taken (dragged) into the questionnaire in a previous page, I still keep receiving this warning in the debug mode:

The variable "X" has not been asked on a previous page during this interview. Therefore value() cannot determine any answer, yet.

how could I solve the problem?

best regards,

Answer 1

Without further information (namely, the debug information), I can only guess:

1) Did you start testing the questionnaire on the page with the question or before?

2) Did you confirm that the variable name is correct - it may be different from the question ID (see tab "Variables" and the Variables Listing)
