I'm new to MS Access and need advice. 

How can I set up my Purchase Order form so that when I select a product using LOOKUP three other fields  in that form automatically populate with the corresponding record/info for the specific product selected? (the other fields are "Product #" and "Unit Price".

I apologize for any information I've failed to provide, but will be happy to give any additional information. Thank you very much for any assistance you can provide.
