I have a question about how to add data manually to the attribute table of a shapefile. Whenever I add data to the file or need to change data in the file, I right-click on the layer and select "Edit features". Then I open the attribute table of the file and begin adding/changing data. I save my edits, save the entire file, and then stop editing. The data is saved in the attribute table. The problem I am having is that the data I add to the attribute table never shows up on my map (I have chosen to add the data to my map as a point -- the points are labeled by the values in a selected column)
What am I doing incorrectly?
