Base - form with data from two tables

Hello, I have two tables with ID Leden (Integer), how do I maintain certain data from table 2 into a form based on table 1. e.g. Form table 1 gives all fields, but i need address field from table2.
Help?

Hello,

You should have a relationship established between the records of the two tables. Table two will have its’ own ID field but additionally a second linked field containing the ID of the record it relates to in table one. Most often this is a one-to-many relationship.

Then on the form you have the table one records and establish a sub form with table two records. There is a property to link the two. This allows the sub form to display related records of the form.
