This part of code shows 0 or undefiend at ...

No it doesnt

This is the same as before, you post a fragment of code that does not compile, does not run, does not show the problem

Maybe it shows the problem on your machine, where the code is complete and compiles and runs,

but over here on my machine it shows that you posted incomplete code which cannot help you fix your problem

huck guesses that you're loading the wrong .pm file but thats too generous on his part

The problem is you dont want to do what is required to solve the problem, which is keep deleting parts of code which have nothing to do with the problem, until you're left with a short piece of code which does reproduce the problem

But you keep posting fragments and hoping that will help you solve it
