Needing help with Macros and error 400

I made this spreadsheet for tracking purposes for work. Everything was running smoothly yesterday until they had me add 5 new people to the list. Now there are 5 separate names Dave, Diana, Kathy, Shawn, and Devante. Where if you click on their names at the top of the Tool page you get error 400. Whereas if you choose a different product for a different name to click on they work fine for all others. I have attached the document. Any help would be greatly appreciated.

Thanks!
Jessica
