This is for the people who didn't understand why it wasn't working skip over this if you haven't tried it out..... When adding items make sure you change the order number property on the item so they are in order or it will not work right if you skip numbers or there is the same number for each item. For example lets say you have two items added. When you first added the items the items were both set with the same order number so the first one can stay 0, but the second one has to be either be one more than last item or in this case it would be 1. If you still don't understand look at Images.
