it's a multiply combined with an assignment

arrIns.indexOf("24");

=2

or

var something = "44";
arrIns.indexOf( something ); // not a string

=15

<pre>Well .. indexof arrIns[i] as a parameter can i assign.. 

arrIns.indexOf(newArr[j]);
for(var j=0; j<18; j++)
{
	document.write( arrIns[j] + " : " + arrIns.indexOf(arrIns[j]) + "<BR>" );
}
Output is:
1 : 0
21 : 1
24 : 2
28 : 3
42 : 4
48 : 5

// **NEW** add leading zero to numbers < 10

// these also need leading zero if < 10
var arrIns  = [ "01","21","24","28","42","48",
                "12","23","34","36","37","46",
                "03","18","19","25","44","45"  ];

var allLucky = arrIns.toString();

var arrLot  = [];
var arr     = [];
var count   = 0;
