Added Background Not Working

Hi Folks,

I am developing a course which has Javascripts included on every single slide. I have taken a Javascript for fetch a current time and date almost 60% slide. And other than that taken a Javascript for a every slide it has mentioned the Background Javascript.

Here is the problem: If I am using only same Background change Javascript in few slides it perfectly works. When it come to multiple Javascript or multiple times of same Javascripts. It doesn't work even I tried using Javascript in master slide. Still it is showing multiple copies in User.js

Here is the Javascripts which I am using in course.

Date and Time: Execute Javascript on timeline start

ar currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear();
var player = GetPlayer();
var newName = day + "/" + month + "/" +year
player.SetVar("DateValue", newName);

var currentTime = new Date()
var hours = currentTime.getHours()
var minutes = currentTime.getMinutes()
if (minutes 
minutes = "0" + minutes
var suffix = "AM";
if (hours >= 12) {
suffix = "PM";
hours = hours - 12;
}
if (hours == 0) {
hours = 12;
}
var CurTime =  hours + ":" + minutes + " " + suffix ;
player.SetVar("TimeValue",CurTime);

 

For Background Change:

document.body.style.backgroundImage = "url('img_tree.jpg')";

 

Can anyone help me to slove this problem.
