Why won't the table insert a value?

Hello, I am currently having trouble on inserting a value. Every time I do it, it gives me an error. If you know anything about this error or what it means and how I can possibly fix it, please let me know. Thanks! (And also, if you need any more information, I'd be glad to get you what you need.)

Error:
