Access query to combine two access tables into one

I have an Access database with two tables. Table 1 has 18000 records in the database but is missing or has erroneous information in two fields. Table 2 has the correct information. I need table 2's information to update table 1. ## Deliverables I will zip up the database to the winning bidder. The database structure of table 2 has four fields. Table 1 has around 25 fields. I need the information from table 2 to update table 1. Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. ## Deadline information I need it by this weekend.
