You can either add help text to the form field definition, which will be
displayed in the Word status bar, or you can add a pop-up message run from a
macro on entry to the field. The best bet would be the former with an
autonew macro in the form template to pop up a box referring users to the
status bar.
That macro might be something like
Sub AutoNew()
Set Balloon = Assistant.NewBalloon
With Balloon
.Text = "Refer to status line at bottom of screen for field entry
details"
.Button = msoButtonSetOK
.Animation = msoAnimationBeginSpeaking
.Show
End With
End Sub
or without the help assistant
Sub AutoNew()
MsgBox "Refer to status line at bottom of screen for field entry details", _
vbInformation
End Sub
