proper referencing of hashes returned by fetchrow_hashref . . .

[Richard Schilling]

Just a quick question, and perhaps it's a Perl language question.  I 
forget, but why do you have to reference a hash with a double "$$" when 
you use fetchrow_hashref?

        [-
        use DBI;
        # code to open connection, run query, etc . . .
        -]
        [$ if $hashed_row = $query->fetchrow_hashref $]
        fieldname: [+ $$hashed_row{'fieldname'} +]<br>
        [$ endif $]
Don't know why but for some reason I'm drawing a blank . . .

Thanks.
