That gives me the following:

<Python Method object at 0x8ac11b8>_frame

>for calling the method test_frame  from method test use this:

That throws an error. Python thinks *_frame* is a variable, whereas the 
entire concatenation is the variable I need to call (your *test_frame* from 
method *test* above).

Any other ideas?
