Trial Balance Not Balancing. Please Help!

The objective of this case is to go through Best Bicycles, Inc.'s accounting cycle for the month of December, 2015. Best Bicycles, Inc. is a merchandiser that sells bicycles.

I did not know what all information would be needed so I included the instructions as well as what I have completed. If someone could please show me why I just cant seem to get my trial balance to add up I would really be appreciative. I have probably spent a good three hours on simply trying to get it to fit, and can't seem to progress. Also cannot get ahold of my professor for any help.
