Summary

This article shows you how to concatenate multiple fields for use in a form or a report. This is especially useful in a mailing label report when some fields are Null or empty. Null fields can cause blank lines to be printed on a report. Additionally, you may want to be able to copy and paste an entire name and address from a form into another application, such as Microsoft Word.

More Information

By using the IIf() and the IsNull() functions, you can determine if a field is blank. If a field is blank, it returns an "empty" value. Chr(13) and Chr(10) are used to add a return and a line feed character to the text box.

Follow these steps to create a concatenated field that eliminates blank lines. This example uses a form, but the same steps also apply to reports.

  1. Open the sample database Northwind.mdb.
  2. Create a new form that is based on the Employees table, and open it in Design view.
  3. Add a text box control to the detail section of the form, and then set the following properties.

    Text Box
    ---------------------------------------------------------------
    ControlName: Full Address
    ControlSource:
    =IIf(IsNull([FirstName]),"",[FirstName] & " ") & _
    IIf(IsNull([LastName]),"",[LastName]& Chr(13)& Chr(10)) & _
    IIf(IsNull([ADDRESS]),"",[ADDRESS] & Chr(13) & Chr(10)) & _
    IIf(IsNull([CITY]),"",[CITY] & ", ") & _
    IIf(IsNull([REGION]) ,"",[REGION] & " ") & _
    IIf(IsNull([PostalCode]),"",[PostalCode])
    CanGrow: Yes
    CanShrink: Yes
  4. Open the form in Form view. Note that there are no blank lines, even if some of the fields in the Employees table are blank.
