                              ' Value-1',
                              ' Value-2',
                              ' Value-3',
                              ' Value-4',
                             ],

The values do really have a "space" in front. I didn't see that until you requested the dumper output.

they also have a "-" in them as well. Not sure if that is causing the issue.

But when doing a standalone print of:

Code:

print $hash1{"Value-1"};

Seems to work fine.

The '-' is not a problem since the key is a string; what is a problem is that ' Value-1' is not the same that 'Value-1', since the the space in front counts as part of the key.

There is no $hash1{' Value-1'}, but there is a $hash1{'Value-1'}
Correct what it would become the keys, in the array, in %hash
