I think it's better to create a set (right click on [Customer Name]->Create Set->then go to the Condition tab and select By formula and type:
[Order Count]=[Return count]
After that drag this Set into Filters (on the Canvas).
The problem is that you mix the aggregated fields ([Order Count] and [Return count]) with non-aggregated field [Customer Name]. If you add attr([Customer Name]) I don't think it will help you.
Thanks lot ..when I am using ATTR() it is creating as measure ,But it should as Dimension.. need not to aggregate..
