Script not working on IE or Edge, but works in Chrome and Firefox

[dlrobioh]

1) Script Title: randompic.js

2) Script URL (on DD): This is from a third party that used a DD script but I don't know the URL

3) Describe problem: Script is below. As I put in the title - not working in IE or Edge, but works in Chrome and Firefox. My system is windows10 pro with ie11, Edge 25.10586.0

picList = new Array(
        "images/banner/Specials2.jpg",

	);

		document.randPic.alt = altList[randomNum];

                // rotate pic every 20 seconds
                setTimeout("choosePic()", 5 * 1000);

I figured out what was causing the issue.

Extra commas behind the last entry in each of the Lists.
