The process of launching a Word document from Access and passing information to it requires a few steps.
First of all, in your Access VBA environment, you must set references to Microsoft Office Automation library and Microsoft Word Objects Library. (Assuming Off 2000, this would be ver 9.0)
Here is an example from Microsoft of launching a Word document in VBA and then writting specific data to bookmarked locations within the word document.
Private Sub MergeButton_Click()
On Error GoTo MergeButton_Err
Dim wordApp As Word.Application
' copy the Photo control on the Employees form.
DoCmd.GoToControl "Photo"
DoCmd.RunCommand acCmdCopy
' start Microsoft Word.
Set wordApp = CreateObject("Word.Application"
With wordApp
' Make the application visible.
.Visible = True
' Open the document.
.Documents.Open ("c:\My Documents\myMerge.doc"

' Move to each bookmark and insert text from the form.
.ActiveDocument.Bookmarks("First"

.Select
.Selection.Text = (CStr(Forms!Employees!FirstName))
.ActiveDocument.Bookmarks("Last"

.Select
.Selection.Text = (CStr(Forms!Employees!LastName))
.ActiveDocument.Bookmarks("Address"

.Select
.Selection.Text = (CStr(Forms!Employees!Address))
.ActiveDocument.Bookmarks("City"

.Select
.Selection.Text = (CStr(Forms!Employees!City))
.ActiveDocument.Bookmarks("Region"

.Select
.Selection.Text = (CStr(Forms!Employees!Region))
.ActiveDocument.Bookmarks("PostalCode"

.Select
.Selection.Text = (CStr(Forms!Employees!PostalCode))
.ActiveDocument.Bookmarks("Greeting"

.Select
.Selection.Text = (CStr(Forms!Employees!FirstName))
' Paste the photo.
.ActiveDocument.Bookmarks("Photo"

.Select
.Selection.Paste
End With
' print the document in the foreground so Word
' will not close until the document finishes printing.
objWord.ActiveDocument.PrintOut Background:=False
' Close the document without saving changes.
objWord.ActiveDocument.Close SaveChanges:=wdDoNotSaveChanges
' Quit Microsoft Word and release the object variable.
wordApp.Quit
Set wordApp = Nothing
Exit Sub
MergeButton_Err:
' If a field on the form is empty
' remove the bookmark text and continue.
If Err.Number = 94 Then
objWord.Selection.Text = ""
Resume Next
' If the Photo field is empty.
ElseIf Err.Number = 2046 Then
MsgBox "Please add a photo to this record and try again."
Else
MsgBox Err.Number & vbCr & Err.Description
End If
Exit Sub
End Sub
