Re^2: Not meaning to add values to a hash ("autovivification")

Thanks. I had used 'exists' before I tried 'defined' with the same results.

What I am trying to accomplish is to only reference the element in the hash if it actually exists. I had also tried to do an if statement where the hash element would have to equal the correct key, but I received a multitude of "Uninitialized value...".

If one side of the comparison is uninitialized (due to not existing), then Perl warns.	[reply]
