at tim ... left and right are reserved keywords in mysql ... if you wish to use them as field names, you have to enclose the field name in backticks (`)

alright, got it fixed. seems to be an error with mysql when you're using the columns named as 'left' or 'right' so i just changed mine to 'lft' and 'rgt'. if anyone seems to have any issues, contact me and i will help you out. good tutorial hostman! now i will go work on editing and deleting since i pretty much have the idea of it now.
