Button not working as expected

The sketch below works fine in the p5.js web editor but when I export it and upload it to the server the buttons do not work properly. Button c and d are the colors I want them to be but a, b, e, and f are the default color. Is there something I am not seeing in the code?

<var bgcolor;
var abutton;
var bbutton;
var cbutton;
var dbutton;
var ebutton;
var fbutton;

function preload () {
bsong = loadSound(“https://ia801401.us.archive.org/28/items/ME2020-09-15/magnolia2020-09-15d01t01.mp3”);
csong = loadSound(“https://ia601402.us.archive.org/24/items/ds2020-09-24/02%20My%20Baby’s%20Coming%20Back%20To%20Me.mp3”)
}

function setup() {
createCanvas(400, 400);
bgcolor = color (200, 140, 160);

let acol = color(255, 213, 120, 100);

abutton = createButton (“Button A”);
abutton.position(10, 10);
abutton.mousePressed(changeColor);
abutton.style(‘background-color’, acol);

let bcol = color(170, 123, 200, 100);

bbutton = createButton (“Button B”);
bbutton.position(150, 10);
bbutton.mousePressed(btogglePlaying);
bbutton.style(‘background-color’, bcol);

let ccol = color(230, 210, 200, 100);

dbutton = createButton (“Button D”);
dbutton.position(10, 50);
