>But I thought earlier you told me I have to put the function in B part? after the first wave?
Yes, and I thought, I repeated that in my previous comment :)
Okay, the flow is as follows:
A) Registration questionnaire with Opt-In
B) Questionnaire displayed immediately after confirmation + mailSchedule()
C) Another questionnaire done some time later (in two weeks or such)
So, I did not get A1/A2 in your description. Hope, now its clearer?
> Do we have to make everything online (out of test phase) to be able to test it?
No, the debug mode will work fine. But you have to start in the very first questionnaire, and already register the email address in debug mode.
> for the personal information page there is a information such that this is gonna be continued later
You are sure, this is the debug information in the upper right corner of the window? See
