Not quite. You have a minor syntax error:
//Lets get the users health colors!
if($fetch->health >= "88"){
$color = "Green";
}elseif ( ($fetch->health <= "87") && ($fetch->health >= "77") ){
$color = "Yellow";
}elseif ( ($fetch->health <= "76") && ($fetch->health >= "20") ){
$color = "Orange";
}elseif ( ($fetch->health <= "19") && ($fetch->health >= "1") ){
$color = "Red";
}
That should work. You had the right idea.
