Problem with associative array

[jatuporn]

I try to write a program that reads a file with two fields.The first field is a 
costumer ID and the second is the costumer name by using " ! " as a seperator between 
2 fields. Store costumer ID as the key and the costumer name as value into a hash. 


My code is below, I have a problem that $info{ $key} does not show the value. What is 
the problem ? How to change it? 

Thank you.


 ***** myfile.pl ***** 

$filename ="costumer.txt"; 
open(FILE,$filename ) or die ("can not open file : $filename");

while ($line = <FILE>)
{       
        $line =~ s/\s+/ /g;
        ($id,$name) = split(/!/,$line,2);
        $info{$id} = $name;
}
print "Enter id:";
$key = <STDIN>;
print ("ID: $key  NAME : $info{ $key} \n");


***** costumer.dat ******
001!test1
002!test2
003!test3
