If you have unbound text boxes you need to tell Access where to put the information the user entered. You will need to run some SQL to update the table you want to update with the data that the user entered. You probably want to create an Append query, but there are several questions you need to answer:
1. Are you always going to append new data?
2. Do you need to check to make sure you don't have duplicates?
3. How will the user edit existing records?
