My guess is that the variable substitution is being done when the button is created rather than when it is clicked. I l like to use namespace in these instances so I can just call the full variable name from inside the procedure.

In Hypermesh customization, I prefer using hwtk rather than tk because there is a very helpful application: 

In that application, learning and testing hwtk is very easy. 

Plus, python is supported and docs:

Happy scripting!
