Hi, I am developing a client database that starts on a client form that has a command button to update client visits. The wizard only lets me link the forms with one field for matching.<br><br>I have a client number consisting of 3 fields: Location, year and client ID. Need to link the forms with all three to show the correct visit info for clients.<br><br>The onclick event procedure is<br><br>Private Sub Visits_Click()<br>On Error GoTo Err_Visits_Click<br><br> Dim stDocName As String<br> Dim stLinkCriteria As String<br><br> stDocName = "Visits"<br> <br> stLinkCriteria = "[Client ID]=" & "'" & Me![Client ID] & "'"<br> DoCmd.OpenForm stDocName, , , stLinkCriteria<br><br>Exit_Visits_Click:<br> Exit Sub<br><br>Err_Visits_Click:<br> MsgBox Err.Description<br> Resume Exit_Visits_Click<br> <br>End Sub<br><br>Can I add the other fields somehow into the stLinkCriteria.<br><br>I have tried several ways but get Type Mismatch and other error messages.<br><br>Please Help!
