you should use .tostring() method on number object:

    var st = cboxval.tostring();

otherwise can't find defining numall variable, had replace

var cboxval = numall;

with:

var cboxval = numall === undefined ? 0 : numall;

in order able perform mys tests.

here have updated version of js fiddle.
