My db is for samples received. I need to have more than one entry per ID - ie, I get a sample with a unique ID, then later receive another under the same ID (either a new sample or a second aliquot of the original).
How do I do this? (I have seen it in other Access db's....there is a box with a + just to the left of the Sample ID field, but I can't tell how they inserted them there.
Thanks for your help!
