I am still having problems with my primary key.
I am using "Unit Number" as my primary key in my main form. I would like to use a command button on this main form to go to the related record in another form in order to enter and view data. It seems as though I have the link established, however when I try to save records in the second form, it claims that I have a null value in the primary key (Unit Number).
Would this be something that's caused by an incorrect relationship??? How could I correct this (or even find out where the problem is)???
Thanks in advance for any advice or ideas.
