Hi Everyone,

I am having trouble finding a way to work through a 2 member array and
search for rows that have identical values.

MyArray [0][0] = 2000,  MyArray [0][1] = "t"
MyArray [1][0] = 2000,  MyArray [1][1] = "f"
MyArray [2][0] = 2001,  MyArray [2][1] = "t"
MyArray [3][0] = 2001,  MyArray [3][1] = "t"

I want to find out that rows 3 and 4 in the above array have identical
values.

Bill, I'm not sure if this is what you're looking for:

<script type="text/javascript">
var myArray = new Array(
	["2000","t"],
	["2000","f"],
	["2001","t"],
	["2001","t"]);
	
function compareValues()
{
	var x;
	for(x=0;x<myArray.length;x++)
	{
		var y;
		var z = x+1;
		var value1 = myArray[x].toString();
		for(y=z;y<myArray.length;y++)
		{
			var value2 = myArray[y].toString();
			if(value1 == value2)
			{
				//Execute your code here
				alert("myArray["+x+"] ("+value1+") =
myArray["+y+"] ("+value2+")");
			}
		}
	}
}
</script>


HTH,
Harry
