I am getting "you should only be displaying one letter in your foreach loop".

I am getting this message "You seem to have too many letters. You should only be displaying one letter inside your foreach loop."

When I preview I see the each of the letters echoed out once as expected. Not sure what is wrong here.

$letters = array("D", "G", "L");

echo "My favorite ";
echo count($letters);
echo " letters are these:\n";
foreach ($letters as $letter){
echo $letter . "\n";
echo ".";

I redid this code challenge again and the only thing I see different between yours and mine that passed was the addition of the "\n". It is not asking you to display the letters on different lines, just to display the letters in the array. The error may be misleading, but get rid of the newline character and you should pass.
