I am very new to Access and was somewhat thrown into finishing this project for a former employer. I am working on a database comparing old students test scores to current student test scores. I am working with 10 different tests. When I go to input the test scores it says this, “Index or primary Key cannot contain a Null Value”? What does that mean? How can I fix the issue without starting from scratch? Thank again for your help.
Thanks,
Annie
