What I understand from your question is that you want to create a flow report. You can go under 'visualizations' and drop the flow chart in the workspace. Now drop that page you want to see the entry and exit dimansions for in the 'drop zone'. This would give you the results.
If we place a dimension in the exits only - It means the exits from site or from the path and user has taken another path? See the snapshot. Does it mean - after button, 2387 visit exited the site, after country 374 exited the site and so on? OR It has to be interpreted in some other way
