Auto_Deactivate can't find Macro

[CDEG]

I have a simple range copy macro that I would like to have run when the "Data" sheet is deactivated. I defined the name as "Data!RitTest" and used the reference of "Deactivate_Test!RitTest.

The problem I can't fix is that the macro isn't found - I get the error : "Cannot find Deactivate_Test!RitTest.

I assume that I'm doing something fundamentally wrong in either the naming conventions or how I am trying to call the macro. Please let me know if anyone can help me with this problem.

Thanks.
