So if you change Check item ..."_Course_data" exists to Check item ..."_CourseData" exists it doesn't work?
Edit: I didn't ask if it's the same. I was pointing out that spelling is not the same and assumed that was the problem. Det kanske beror på något annat, jag vet inte :P
Thanks for clarifying. I must have stared myself blind on the issue being construct 2 vs construct 2, so I did not see the obvious :).
I apparently works now when all references are the same as he file name ;)
