I have a table of lab tests with fields of [ID], [Test], [TestAcronym]. As people often refer to the tests by their acronyms, I wanted to include the acronyms mingled alphabetically with the full names to allow selection of either in a combo box. I did this with a union query. This created a list with each record represented twice. The problem comes after a test has been selected. No matter what has been seleted, what shows up in the combo box is whatever term (Test or TestAcronym) is first in the list (ie: first alphabetically). What I want to show up is Test whether it or its acronym was selected and no matter which is listed first alphabetically. Any thoughts?
