Re^4: Perl - TK - Listbox insertion problem

I'm not sure why the error message i was receiving was no such file or directory sense all that needs to be done is the text inserts into a listbox widget. What does that have to do with a file or directory. Its a weird error to me.

Citing the documentation (emphasis mine): `$listbox->insert(index, ?element, element, ...?)` [download] Inserts zero or more new elements in the list just before the element given by index. If index is specified as end then the new elements are added to the end of the list. Returns an empty string. You cannot use `or die` for functions returning always the empty string. See also the definition of `$!` in perlvar.	[reply] [d/l] [select]
