SELECT * FROM $user_data_db_name WHERE USER_NAME='$form_values{'USER_NAME'}' isn't interpolating the values the way you thing it is: you're searching for the record where the username is literally $form_values...

Instead of this, try 

$sqlCount = "SELECT COUNT(*) FROM $user_data_db_name WHERE USER_NAME=?
+";
$sth = $dbh->prepare($sqlCount) || die "Cannot prepare: " . $dbh->errs
+tr();
$sth->execute($form_values{'USER_NAME'}) or die "Cannot execute: " . $
+sth->errstr();
my $occurences = $sth->fetchrow_arrayref->[0];

And find out why bind variables are your friend

As an aside, do you really want the table name to be a variable. Could be messy if it gets the wrong value into it.
