Continueing a for loop after a record save

So I am trying to print a packing slip qty box label for each line on a Item FulFilment. I have a working button that calls the client script but it always exits the 2nd for loop after one pass. below is a snippet of the code.
for(var i = 0; i<lineCounts; i++)
        {
            if(i == 0)
            {
                var message3 = "Opening Multiple Label pdf windows. Please click ok and wait for confirmation message.";
                  alert(message3)
            }
        var currentItem = recIf.getSublistValue({
                sublistId: 'item',
                fieldId: 'item',
                 line : i
        });
        var recItem = r.load({
                type: r.Type.ASSEMBLY_ITEM,
                id: currentItem,
                isDynamic:true
          });
        var customerPartSearch = s.load({
