Unique Random Number Problem

[jgd12345]

Hi I have the following script which should generate 3 unique random numbers and store them in the corresponding text boxes when run but it returns an error.

<script>
function addLuckyDip(lineNumber) {
var randomnumber[0] = Math.floor(Math.random() * maxValue) + 1;
var randomnumber[1] = randomnumber[0];
var randomnumber[2] = randomnumber[0];

while(randomnumber[1] == randomnumber[0]) {
randomnumber[1] = Math.floor(Math.random() * maxValue) + 1;
}

while(randomnumber[2] == randomnumber[0] || randomnumber[2] == randomnumber[1]) {
randomnumber[2] = Math.floor(Math.random() * maxValue) + 1;
}

for(var i = 0; i < 3; i++) {
document.lotteryPlayslipForm.elements["drawGameBoards["+lineNumber+"][numbersChosen]["+i+"]"].value = randomnumber;
}
}
</script>

<form name="lotteryPlayslipForm">
<input type="text" name="drawGameBoards[0][numbersChosen][0]" class="text">
<input type="text" name="drawGameBoards[0][numbersChosen][1]" class="text">
<input type="text" name="drawGameBoards[0][numbersChosen][2]" class="text">
</form>

Looks everything OK, except for array initialization. Try this:

[b]var randomnumber = new Array();[/b]
   randomnumber[0] = Math.floor(Math.random() * maxValue) + 1;
   randomnumber[1] = randomnumber[0];
   randomnumber[2] = randomnumber[0];

Cheers worked a treat.
