Upon further reflection, your code shouldn't break even if that line had been deleted. It just looks wrong. My bad.

At this point it might help if we saw @data and @data2. I have a sneaking suspicion that your program is actually behaving correctly.

In the meantime, you wanted to know how to access $name and $ref? As near as I can tell, for each entry $n < $num you can use these:

$keyhash{$id}{MANY}[$n][0] # $name
$keyhash{$id}{MANY}[$n][1] # $ref

Maybe this will help you debug your very very strange data structure...
