I'm trying to use a combo box to select values for a record in a table. In addition to the primary key value and other arbitrary information, three of the required values are a Foreign Key to another table (say field A,B, and C). In the foreign table, A,B and C is the primary key value (combination of the three). How can I (if possible) use a combo box to look up a combination of A, B, and C (in the lookup table) and insert the values into the local record?
Per example, I'm using a table to store checks I've written (in regards to a tax program). A is a State Code, B is a check Type, and C is the type of entity (person, company, etc.) My lookup table uses A,B,C as a PK and then has address information for each of these unique combinations - a late fee check to FL for an Individual must be sent to this addresss.
Thanks for any help!
