Media query part2 challange

I am doing the legacy responsive web design principle. I am confused as to what I am doing wrong please help me. I have gone through the hint and video and still cant see what is wrong. The second part of challenge keeps giving a cross.

p {
  font-size: 20px;

/* Only change code below this line */
@media (max-height: 800px) {/*CSS Rules*/}

@media (max-height: 800px) {
p {
  font-size: 10px;
/* Only change code above this line */

We need to know the exact challenge this is for. Please provide a link to the challenge.

Hi this is the one

You have two media queries for max-height: 800px. This is throwing off the test. Get rid of the one that isn’t doing anything.
