Vincent and All,
After figuring out that broadcast send/get/set does not work i tried to find another solution.
Looked at previous demos and found the solution in reusing the same routines to create the survey-pages into saving the data into the database.
It still needs some work with cWebRadio/cWebCheckbox and a few other classes but technically this works.
In short:
use a routine to create objects with the CreateDynamicObject functions on the surveypage and use the same routine/loop with DynamicObject (with the same ID's) to retrieve the data from the survey-page.
