So I have this code, and I've been fretting over it for several hours now and my friend and I can't find the solution. It display reviews based on a descending ID pulled from a database. This is an endless scroll type of script to eliminate pagination. For some reason when I hit the bottom of the page and run the script, the while loop is iterating through the data twice. So if its supposed to display reviews ID 5 - 10, it display 10, 9, 8, 7, 6, 5, 10, 9, 8, 7, 6, 5; instead of 10, 9, 8, 7, 6, 5. This is going to be a very large bit of code, But I hope you can help me with my problem. Thanks in advance!!
