I have a sharepoint list, my data is brought to a powerapps gallery, this gallery has checkboxes that when pressed add the selected item to a collection. Then when another button is pressed all the items within the collection are checked for matches against my original sharepoint list, and a field is patched to for each.
When ran it returns "Error when trying to retrieve data from the network". This method has worked in similar situations previously, so im unsure as to why it isnt now. Ive browsed for a couple of hours testing solutions, but none have fixed my issue.
My code is:
ForAll(Selected_Attendees1, Patch('CB 2.0 Attendees List', LookUp('CB 2.0 Attendees List', AttendeeAddress = ThisRecord.AttendeeAddress), {DeleteCheck: "Yess"}))
Selected_Attendees1 is my collection. Any help or suggestions would be massively appreciated.
