DDE Argument exchange with Word

[Steve]

Does anyone know how to send a variable text string from
Excel to Word using a DDE argument in an Excel macro? The
following Excel macro will send a specific text string,
but I want to use a variable to define the text string.



Sub WordOpen(customerName)
'
'

Dim WordApp As Object
Dim WordDoc As Word.Document
Dim Chan As Variant

Dim PathName, FileName As String


PathName = ActiveWorkbook.Path
FileName = PathName & "\Test.doc"


Set WordApp = CreateObject("Word.Application")
Set WordDoc = WordApp.Documents.Open(FileName)
WordApp.Visible = True

' Initiate a channel with Microsoft Word.
Chan = DDEInitiate("WinWord", FileName)

' This sends the text to Word
DDEExecute Chan, "[Module1.Begin(""John Doe"")]"

' Want a command to send variable text customerName to
Word, similar to this except it does not work
' DDEExecute Chan, "[Module1.Begin(customerName)]"

' Terminate the channel.
DDETerminate Chan

End Sub
