Why are you mixing PHP and Javascript up like that? And why are you using document.getElementByID? Also, putting spaces in id attributes is invalid.

Clue, just use PHP for this, perhaps a case statement:

switch (true) {
    case $count <= 6:
        $trend = 'super-hot';
        break;

    case $count <= 4:
        $trend = 'hot';
        break;

    case $count <= 1:
        $trend = 'new';
        break;

    default:
        $trend = 'lame';
        break;
}

Hi,

as pty said, mixing PHP and JavaScript code like this is not the right way.

And document.getElementById(ID_HERE) will return an object with the HTML element who has the ID_HERE value. (see more on this here: https://www.w3schools.com/jsref/met_document_getelementbyid.asp)

You should either do this fully in PHP, as pty suggested, or pass the number of comments to JavaScript and have the switch/if elseif there. More info here: https://www.w3schools.com/js/js_switch.asp and here: https://www.w3schools.com/js/js_if_else.asp
