Count up with scoreboard

Dear all,































































































































I've made a website with a count up system made with Java. I've found the code on the internet and now I want to connect it with a scoreboard, that displays a top 3. U may wonder why I would like to have this: on my website, there plays a song that is very popular in the themepark world. Now it plays non-stop on repeat, so for fun I added a counter. There were a lot of questions if it couldn't be possible to add a scoreboard.































































































































Hope someone could help me with this.

The code:

var counter = 0































































































































var timer;































































































































function countUP () {































































































































counter = counter + 1;































































































































document.getElementById("timer_container").innerHT ML = counter;































































































































}
