I would like to generate an ID field that displays the initials of the previously selected platform from a radio menu, along with an incremented number.
The formula I have on my ID field is:
Switch(ThisItem.'Publication platform'.Value, "City Intelligence", "CI", "Data Seeing Room", "DSR", "Intelligence Hub", "IH", "Open Data", "OD") & Text(CountA(Filter('Publication Metadata'.'Publication platform','Publication platform'.Value='Publication platform'.Value))+1)
So ideally what I want is for example if City Intelligence was selected from the radio choice, the ID will be : CI1, then the next logged item CI2 etc.
Am I using the wrong formula? It's worth mentioning that once they click on adding a new item, a pop up window will show up, they will have to select the platform and then it will take them to the Edit Form where the Publication Platform is already prepopulated with the field that was already selected from the pop up. - pics below
