If you "use strict;" you may not use symbolic references, i.e. (mis)use a
variable's name to create a reference to it. That's why I fixed your code
by replacing the variable names with references to the variable I assumed you'd
wish to address.
Maybe you should take a look at the perlref manpage (e.g.
http://perldoc.perl.org/perlref.html) for a better explanation.
As for putting in a literal 'mvb' that was just to demonstrate the usage. Of
course you can replace that with any expression evaluating to any key of
%stp_dirs or whatever.
