External file.

I have a handler in an external file. It is required at the start of the code.

Inside the sub in this file the $bot variable is required but cannot be found.

Another sub (in bot.pl) uses the bot variable, and it doesn't seem to be passed (it too is a handler)

Any ideas?

Could be a couple of things, Maybe a typo error.

Or make sure this isnt wrong:

If you use my in your code its a local variable so wont work in external.

The complete lack of code makes it impossible to help you. This kind of issues are why globals are bad. Instead of using globals you should be passing the variables. Then you would know exactly where and what each value was and you wouldn't have to guess. If you do want help with this though you will have to provide more information and code.

I had this problem when I started using strict in my bots. To declare a variable or hashref or whatever as global, so that all the included files and subroutines can use it, declare it with "our" instead of "my"

Example:
our $bot = {};

Thanks Cer! That works, my lack of understanding of external files it seems was the problem, i was thinking they would work something like php includes.

btw, i couldnt exactly pass them, it was called by a handler correct me if i'm wrong....
