I'm sure that this can be accomplished with a label expression however I opted to create an addition "Label" field with the intention of populating it with a filtered version of the "Streetname" field. I thought I had a handle on how to accomplish this but obviously I am missing something important. Can anyone shed some light on this for me please?
