He Brian,
In Perl, you don't have to declare your variables if you don't want to.

@words=('test','this','that','test');
for $word (@words) {
$count{$word}=$count{$wor
I'll try
$count {$word} = $count {$word} + 1;
The $count refers to a hash called %count. As you are working with only one
element of that hash (the key/value pair with the key of $word), you
reference the element as a scalar (hence the $, not %). It's still refering
