Nope, wouldn't get that error message if I left it out. I call as follows. use Modules::ScriptUpdate;	[reply]

`use Modules::ScriptUpdate;` If you load it like this, your package name should be `Modules::ScriptUpdate` accordingly, or else Exporter will alias `main::script_stats()` to `Modules::ScriptUpdate::script_stats()`, not `ScriptUpdate::script_stats()`, where it would reside in your case with a package name of `ScriptUpdate`... In more detail, the reason is that `use Modules::ScriptUpdate;` implcitly calls `Modules::ScriptUpdate->import()`, which in turn (via inheritance) calls `Exporter->import()` with the first parameter being `"Modules::ScriptUpdate"`. This then is the namespace used by Exporter, not what you specified in the module source with `package`. For this reason - when you use Exporter - package name and filename/path of the module have to match.	[reply] [d/l] [select]

use Modules::ScriptUpdate; The usual thing to do is to have the module name match the package name - ie in ScriptUpdate.pm it would be usual to declare `package Modules::ScriptUpdate;` instead of `package ScriptUpdate;` (as you have done). Cheers, Rob	[reply] [d/l] [select]

Yes, you would get that message if you forgot use: `use strict; use warnings; script_stats(); __END__ Undefined subroutine &main::script_stats called at TLEQUERY.pl at line + 3.` [download]	[reply] [d/l]
