Hi Chris, it is unclear as to what exactly you’re trying to achieve here.
From what I can understand - you have a collection of items (products?) that you want to connect to a repeater, you have attempted to connect these items to the repeater using a dataset? - Have you made sure that you have set-up the links to do this? Make sure that you set up links between the collection & your dataset (this should be done automatically) - and the links between your dataset and the repeater (this is not done automatically) - if this is still an issue let me know, or if I have misunderstood could you clarify the above so we can understand better
I hope you resolve the issue soon, if not contact me and we could work something out!
Thanks,
Elliot
