Hey, just starting with power apps and I have an issue I'd appreciate help with.
I have a multiple selection combobox: ["A", "B", "C", ... ] as an example.
On sharepoint I have this column as a Multiline text. I wish to get all the selected items from this combobox, concatenate them with a ", " as separator, and save that on my sharepoint table as a simple string.
I tried changing the "update" function on my form field to "Concatenate('field', ", ")" but no luck. The error I always get is the "Object needs to implement IConvertible" and I assume it's because the data I'm sending to my sharepoint is not casteable to "multiline text".
Any ideas please?
Thanks
