Hi Andreas,
Thank you for your reply. I have tried this method before and it confused me (referencing the courses data set…) I get the impression that it should be simpler than whats in my head, but I think this might be a too much for me! I currently have 12 dates per course in each fields in the Courses Data Collection for over 50 courses all of which are different dates.
I’m a member of your website wixshow, are there any tutorials on your website for something similar?
