Re: 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);
[download]

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]` [download] 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.	[reply] [d/l]
