Hello I'm B. Morris. Not sure if this is the right place being new to the GeoNet, but figured I would try. I'm using ArcGIS for desktop V10.5.1. I need some quick advice on how to make something work due to a time critical mission I am working. Here is the deal: I wish I could show the table I took a screen shot of. 1. Attribute table named "Building_Clean_up" 2. In the attribute table there are two data columns named "Building_I" and "FAC_NUM". Question is this: How do I copy the data from the "Building_I" data column over to the "FAC_NUM" data column? I have tried everything that I know of thus testing what little knowledge I have. Can someone help expand my 10% factor here? LOL Vr... Brook M.
