Hi all,

I'm quite new to perl and trying to understand some scripts. The code I have trouble with is this:

$TotCst{$AppCode{$ID}}->{$CstType{$ID}} += $InvAmnt{$ID};

from this line, I gather this:

hash %TotCst, nested hash %AppCode, key {$ID} ..and this is where I'm stuck.. what is the ->{$CstType{$ID}} saying? I understand that the result of this is incremented by the value of $InvAmnt{$ID}, it's just the ->{$CstType{$ID}} bit that I don't understand. I can see that -> is used in with references and nested hashes/arrays, but not quite how it makes sense in this line.

If anyone can shed light on this I'd be very grateful.
