Hi, I try to work on Assignment 3-1 from GIS Tutorial 1 (Basic Workbook). I should create a report with two maps. I think, it is same as Tutorial 3-4, but it does not work.
First I create a map document with first layer. After that I think I should create new "Data frame". But first layer is disappearing when I add the new "Data frame". What is wrong?
I use ArcMap 10.0.
