Paginating error with joining tables - php

Question

Need some help if possible?
I’m trying to add pagination to my code.. The problem I am getting is the pagination script works perfectly well without the JOIN statement and the JOIN statement works when I exclude the pagination script so they both work just not together.
It counts the results correctly with both scripts together just wont show the data.
The question is how do I get them to work together as I get an error:
Any help would be grateful
