Oops, try again. It looks like sleepCheck() isn't returning "You're getting plenty of sleep! Maybe even too much!" when numHours is 10. Check your if / else syntax and whether you're using the correct comparison operator.

var sleepCheck = function( numHours ) {
    if ( numHours >= 8)  {
        return  "You're getting plenty of sleep! Maybe even too  much!";
    else  {
        return  "Get some more shut eye!";



the string returned should be an exact match, you have two spaces between too and much, this should be just one space. Maybe there are more mistakes, just copy the string from the instructions
