runMacro() not seeing libName parameter

I put my macros in library ‘explore’ rather than in ‘Standard’ but runMacro() defaults to ‘Standard’ and I’ve yet to find the syntax of a call to get runMacro() to recognize my parameter and accept it as libName, the library to search for a matching function.
I’m uploading an example where you’ll find several of my attempts in function ‘_rangeWalkFn’. you will also see where I hard coded ‘explore’ in runMacro() while commenting out the ‘Standard’ line. with ‘explore’ set as libName the functions under the buttons run. With libName = Standard they don’t.
All suggestions welcome.
Thanks,
Mike
