in reply to
scope of variable
Why are those sub definition inside another subroutine? Did you want them to be lexically scoped? If so you should check that your version of perl makes it default behavior (ie perl6, which I suppose you're actually not using), or that the feature is enabled. But in perl 5.18 this feature is experimental, and should be used with caution.
If you did not want lexical scope for you subs, which they probably do not have (pushes the sub names into the current package's namespace). Actually, I'm pretty your subs are only compiled once, and not each time you enter getValue.
That may have nothing to do with your problem, but since you are speaking of scoping issues ...
