[MS_AccessPros] Primary Index

 

I have a Product table.

The primary key is the Product ID and Color ID. The same Product ID  is available in multiple colors.

Some Products dont have a Color, but I can not update the record without entering something in the Color ID.

I have tried space , but it does not accept it. 

Is there anyway I can have the Color ID as part of the Primary key even though in same cases it is blank/null?

Thanks

Sarah
