I have the following script:

function countdown(auctionid){
    var auctions;
    var divs;


        $.get("current.php", {
                    if(auctions[n] != undefined){


    var cauctionid="auctionid";
    var tauctions=auctionid.split("|");
        if(tauctions[i] != undefined){
            var dd=$('#futu'+tauctions[i]).text();
            var cdd=dd-1;


            if(dhour <=9){
                dhour = "0"+dhour;
            if(dmin <=9){
                dmin = "0"+dmin;
            if(dsec <=9){
                dsec = "0"+dsec;

                var valll=dhour+":"+dmin+":"+dsec;

                var valll="00:00:00";


On the line that reads: if((Timer%10=="0")||(Timer=="1")){

How do i make the 10, a random number between 2 and 12?

You want to use the random() function. There is no version that returns an integer unfortunately, only a float between 0 and 1, so you'll need to do a few operations. Try the following:

var randomNum = Math.floor(Math.random() * 10) + 2;

This should generate a random integral number between 2 (inclusive) and 12 (exclusive). Change 10 to 11 if you want the 12 to be inclusive, of course.

JavaScript random() Method, More "Try it Yourself" examples below. Definition and Usage. The random() method returns a random number from 0 (inclusive) up to but not including 1  A Proper Random Function. As you can see from the examples above, it might be a good idea to create a proper random function to use for all random integer purposes. This JavaScript function always returns a random number between min (included) and max (excluded):

See the answers to this question which also allows you to set the seed value.

Math.random(), The implementation selects the initial seed to the random number generation Note that as numbers in JavaScript are IEEE 754 floating point  Math.random() Return value. A floating-point, pseudo-random number between 0 (inclusive) and 1 (exclusive). Examples. Note that as numbers in JavaScript are IEEE 754 floating point numbers with round-to-nearest-even behavior, the ranges claimed for the functions below (excluding the one for Math.random() itself) aren't exact.
