Thank you!  This worked once I changed the highlighted line. 

function onSubmit() {

if(window == null){
     
     var z = this.document.getElementsByClassName("select2-chosen");

     //if(z[1].innerHTML > 8 ){
     if(z[0].innerHTML > 8 ){
          alert('Please select value less than 8');
          return false;
     }
}
else{

     var quantity = $j('#quantity').val();
     if(quantity > 8){
          alert('Please select value less than 8');
          return false;
     }
}
}
