Hi, I have used access in the past but very little. I need help setting up a table that I can make relationships to another table. Here's what I need.

I need a table(s) that I can log samples of medications into. It needs to have a drug name, dose, lot #, expiration date, and #of samples. As we get samples, these will be logged into here via a form made from the table (I've already done this exactly as stated). I will need to be able to get a total from the number of a certain dose of medication i.e. amoxicillin 500mg (all of the lot numbers added together).

Now, another table(s) needs to have samples signed out. It needs to include pt. name (first and last), date, drug, dose, lot #, exp. date, #of samples, ordering practitioner, and clinic. What I want to happen is when I sign out the Amox 500mg #30 with a specific lot #, it will remove the number from that specific lot # in the inventory table and reduce the number of Amox 500 total (all lot #s).

Does this sound too complicated. I tried to set up one table for the sign out process, but suspect it's too many variables. The primary key I was thinking would be the lot # but i need to be able to use it more than once if I get 100 samples and only use 30 at a time.

Would someone be willing to offer some advice!!!?? Thanks, Robin.

If you have the Northwinds sample database installed, check their inventory sample.
