Symbols don't show, variable conflict?

I am running Autocad Mechanical 2010. When I run the Tolerance command (geometric tolerancing), I cannot see the "symbols" for type of tolerance I want to use, i.e., Perpendicularity, Flatness, etc. All I see are letters in the pop up menu such as i j k l m. I believe it is a conflict with other variable names that prevent the slides in the slb of the tolerance command from showing. Any ideas where they might be? In the .mnl file? In my .mnu file? Is there such a thing as .mnu any more?

Well, I'll answer my own question. After a little thought, I decided to look at every routine (lisp, mnl, etc) that was loaded. I went through each and every one, and lo and behold, I came to one called Steel.lsp by Stephen R. Taylor and discovered that he had all kinds of variables in the routine that were not "localized" by the usual defun: x (/ var1 var2) method of a lisp routine. Every setq variable in his routine was "global" and thus conflicted with those open variables in AutoCAD. That's why I couldn't see the GeoDim symbols. After I localized the steel.lsp variables, wha-la, there they were.
