random numbers

i ve got this code from a website but i can't seem to generate 6 random numbers between 1 and 49, can some1 have a look at the code and see what needs changing. thanks

function getUniqueRandom (number) {
    var numberlist = new array();
    for (count = 1; count <= number; count++) {
        numberlist[count] = count;
    }
    this.rand = new array();
    for (count = numberlist.length - 1; count > 0; count--) {
        picked = math.floor(math.Random()*count)+1;
        this.rand[count-1] = numberlist[picked];
        numberlist[picked] = numberlist[count];
    }
    return rand;
}

num = new getUniqueRandom(6);

Rand0 = num.rand[1]
Rand1 = num.rand[2]
Rand2 = num.rand[3]
Rand3 = num.rand[4]
Rand4 = num.rand[5]
Rand5 = num.rand[6]

hello luke, did you try this?
myArr=[];
function shuffle() {
     if (random(50)) {
          return 1;
     }
}
for(var i = 1; i < 50; i++){//this section changed...
if(i<10){
     myArr.push("0"+i);
}else{
     myArr.push(i);    
}    
}
myArr.sort(shuffle);
for(i=0;i<6;i++){
_root["Rand"+i]=myArr[i];
trace("_root[Rand"+i+"]="+_root["Rand"+i]);
}

hello,

try also this one...

function randomnumbers(lowest, highest, count) {
      var randomnums = new Array();
      if (count<=highest-lowest) {
            var nums = new Array();
            for (var i = lowest; i<=highest; ++i) {
                  nums.push(i);
            }
            for (var i = 1; i<=count; ++i) {
                  var randomnumber = Math.floor(Math.random()*nums.length);
                  randomnums.push(nums[randomnumber]);
                  nums.splice(randomnumber, 1);
            }
      }
      return randomnums;
};
myrandom = randomnumbers(1, 49, 6);
trace(myrandom);

Hi,

try this one...actually there not much changes on your code..it's just some of  your keywords are incorrectly typed..like "math.floor" it should be Math.floor....k just see this...

function getUniqueRandom (number) {
    var numberlist = new Array();
    for (count = 1; count <= number; count++) {
        numberlist[count] = count;
    }
    this.rand = new Array();
    for (count = numberlist.length - 1; count > 0; count--) {
        picked = Math.floor(Math.random()*count)+1;            
        this.rand[count-1] = numberlist[picked];
     numberlist[picked] = numberlist[count];
    }
    return rand;
}

num = new getUniqueRandom(6);

Rand0 = num.rand[1])
Rand1 = num.rand[2]
Rand2 = num.rand[3]
Rand3 = num.rand[4]
Rand4 = num.rand[5]
Rand5 = num.rand[6]

best regards!
