Question : Operation Must Use an Updateable Query

I have a website that uses an Access Database. I'm able to read from the database without any problems. However when I try and update a record in the database I get the Operation Must Use An Updateable Query error. I'm assuming this is a permission problem but I can't figure out where my persmissions are wrong. The permissions are listed below. Any help would be greatly appreciated.
