Hi Bali,

You can insert all of the fields in the one go and then arrange them, though
that is not really very satisfactory.

Or you can down load the sample file under the "Display list of merge fields
in a non-modal dialog box" topic under the "Setting up the main merge
document" section of the "Mail merge in Word 2002" item on fellow MVP Cindy
Meister's website at:

http://homepage.swissonline.ch/cindymeister/MergFram.htm

There is however a slight error in the code behind that form in that
document which means that the Insert Field button on the form does not work.
Double clicking on a field in the list does however work.

To correct the error in the code, right click on the frmMergeFields under
the Forms item in the Project Explorer in the Visual Basic Editor and select
the View Code item.  Then locate

Private Sub cmdInsertFields_Click()

and change it to

Private Sub cmdInsertField_Click()

then click on More Items on the Task Pane and insert another field, close
the window, click on More Items on the Task Pane again and repeat these
steps for all the fields.
