I have this as my on check function of checkbox in gallery
Collect(colNotification,ThisItem.User.Email)
and I thought I could just use this
Remove(colNotification,ThisItem.User.Email)
to remove on the uncheck. As I've done plenty of times. However I've never done it with a people field and it obviously behaves differently? as I'm getting an error to say the function remove has some invalid arguments.. however I don't know what they are ! have tried a few different variations but no avail. In the collection itself the column is called Value so obviously have tried that both stand alone thisitem.value and thistime.user.value.. however none works.
What am I missing?
