Thanks for the guidance. I took what you suggested and worked it to fit with what I needed. What I ended up doing was using the constraint and constraint_message fields. Using pulldata("@geopoint", ${location}, "x") and pulldata("@geopoint", ${location}, "y"), I was able created a bounding box of the area so that when someone places a geopoint within the area it will give an error message. It took a little while troubleshooting with the coordinates and the <> and connectors (and/or) to get it right but it seems to be working now
