Here is the basic idea:
Tables-
1) Cars
2) Parts
Query-
Cars linked to Parts
I want to create a form that starts with a drop-down. I would pick the car I want which then shows me a list below it (subform) of all the parts related to that car. Then I want to click on the part in the list and have it show me all the information on that particular part in another subform. How would you do this?
