Hi
I have an app connected to a Sharepoint contacts list. I am wanting to add to the notes section in this list, which already has information in some cases. I have made that column (notes (comments) ) an enhanced rich text column.
In my app I have a gallery with populated information from the sharepoint contacts list. I have an HTML text box to show the information already in the notes(comments) column. I added a rich text editor into the gallery, so information can be added to this column.
The first image shows the screen set up
The second image shows the patch formula I used first. This works, however, it just changes the information not add to it.
the third image I tried @Anonymous Young's videos showing this formula, however, I had no joy with that either. just tells me requires title and then when I add it doesn't recognise it.

Can anyone direct me as to where i'm going wrong
