Found a solution to placing the link in the address portion of a hyperlink datatype field. As I entered above, the key was finding ".value" in "Similar Posts" on this forum. Will be a lot of repetition but is saves me from more than 1,200 manual entries. Would check the "Solved" control but don't know where it is
Code:
Private Sub LetterAddress_Click()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strAddress As String
Set db = CurrentDb
Set rs = db.OpenRecordset("Letters")
rs.MoveFirst
Do While Not rs.EOF
strAddress = rs!LetterId + ".pdf"
rs.Edit
rs("LtrLink").Value = "#" + strAddress + "#"
rs.Update
rs.MoveNext
Loop
End Sub
