Add all the fields you want to combine into the query your form is based on. You do not have to set up controls for those fields, jus add them to the query, just use a text box for the FullAddress. You can now refer to them as Me("Address 1"), Me("Address 2") etc (PS it is best not to have spaces in your field names). If VbCfLf doesn't work (It does in 2000 but I'm not sure about 97) then use cr = Chr(13) & Chr(10) or replace cr in the expression with Chr(13) & Chr(10).
Another way is to use an expression in the query to the same effect. In your query, set one of the fields to FullAddress: [Address 1] & Chr(13) & Chr(10) & [Address 2] etc, making sure that the fields you want to combine are in the query otherwise it will ask you for them and then set up a form control eg txtFullAddress based upon the FullAddress expression.
