in reply to use of unitialized value

Try dumping the contents of $inventory{$itemcode} to see what's actually in it (using Data::Dumper: 
print Dumper($inventory{$itemcode});
# or even:
print Dumper(\%inventory);

That way, you can verify that the hash values contain what you think they contain.

    Hmmmm...
    The funny thing about this error message is that it happens whether there is a value in 

    $inventory{$itemcode}[2]

    or not. The loop will generate the error in each iteration.
    The value is from a web page form input, so I thought the problem might be a string/number conversion, but the error message doesn't indicate that.
