Peari,
The following posted by Cindy Meister may help:
The ampersand is dedicated to marking a "hot-key" for each selection in
the drop-down list. KB article Q125892 has the details.
The only solution I know is to use a macro that, when you exit the
dropdown field, sets an immediately adjacent text box to the "label" of
the selection, then sets the drop down to a selection that is a space (in
the example, the first entry). For example:
Sub DisplayDropDownContent()
Sel = ActiveDocument.FormFields("DropDown1").Result
ActiveDocument.FormFields("Text1").Result = Sel
ActiveDocument.FormFields("DropDown1").DropDown.Value = 1
End Sub
