Hey friends,

I am struggling with a problem. I have a hash, example:

 $myHash{$customer}{money}

The $customer is a value that I get by analizing a database everyday. This means, that everytime I run the script, there might be a new customer. The result of the hash is a scalar (money they spent).

I want to write a procedure how to extract the money they spent, by each $customer. I tried somehow like this:

 foreach $customer (keys %myHash){
 $money_spent = $myHash{$customer}{money};
}

Ofcourse, I am aware this doesnt work as i want, because the $money_spent will change everytime another $customer comes.

But I don't know how to get it done efficiently. I DO NOT WANT TO USE IF STATEMENTS HERE, LIKE THIS: 

 foreach $customer (keys %myHash){
   print "$customer \n"; #--check what customers are there
   if ($customer eq 'NAME-OF-CUST'){
      $money_spent_name_of_cust = $myHash{$customer}{money};
   }
...
}

I dont want to manually write down an IF statement for every $customer. There has to be a way, to store the values for each customer into a variable $money_spent.

Ideas very appreciated. David
