So I am building a quote database in an existing customer database for the company I work for. I have a master table where the quotes are stored once entered in the form. The first section is basic either a manual entry or using combo boxes tied to tables, but when I get to the parts selection I would like based on the description selected it to auto fill the cost per part plus the selling price. I have a single table built for this listing part description, cost price, and list price. Do I make the connection in the table or do I make the connection in the form? Based on which one how do I do it?
