Can't get slice to work

var OrderNo = varCovArray[6];
var OrderNo6 = varCovArray[6].substr(7,6);

If my order number is 13 characters the above works.

But if my order number is more than 13 characters, it doesn’t. I need to pickup the last 6 characters of the order number for any string length.

So, if my order number is 1105120908528_T2, the result is “528_T2”.
If my order number is 1105120985597, the result is “985597”.

below is what I am working on.

var DataToEncode = $arg1 + "90000";
var isbn10 = ("ISBN-10: " + $arg2.substr(0,1) + "-" + $arg2.substr(1,3) + "-" + $arg2.substr(4,5) + "-" + $arg2.substr(9,1));
var isbn13 = ( "ISBN-13: " + $arg1.substr(0,3) + "-" + $arg1.substr(3,1)  + "-" + $arg1.substr(4,3) + "-" + $arg1.substr(7,5)  + "-" + $arg1.substr(12,1) );
var varCov= $arg3;
var sku = $arg4;
var coverText = $arg5;
var mycovertext = new File(coverText);
var arcPath = "/Volumes/McGraw Hold/" + $arg4 + "/" + $arg4 + ".indd";
var arcPathpkg = "/Volumes/McGraw Hold/" + $arg4 + "/Source/" ;

var varCovArray = varCov.split("-");
var varCovSwitch = varCovArray[0];
var spine = varCovArray[1]
var volNum = varCovArray[2];
var jobQtyDisplay = varCovArray[3]
var jobQty= parseInt(varCovArray[3]);
var LocCode = varCovArray[4];
var AccessCodes_BkCvrCount = varCovArray[5];
var OrderNo = varCovArray[6];
//var OrderNo6 = varCovArray[6].substr(7,6);
var OrderNo6 = varCovArray[6].slice(-6);

String.substr(start,count)
If start is a negative number, the function counts from the end of the string and count is an optional argument

I see what my partner did here, she was trying to “subtract” rather implementing the position. I’ll fix it up and let you all know how it goes.
