Re: Do values from string exist within array?

[Eily]

How do you print your dump? The fat comma (=>) makes it look like a hash (but since it's just a list it could indeed be an array), but you have twice the same key, so it's not possible. And since your variable is @GrpIDs, it has to be an array.

You should look at grep and Text::CSV for your problem. But I can't help any further unless I have the right data structure.
