Form Validation where 1 field depends on another fields value
Hi
I have a form where I have 2 fields AgencyDirectCB - this has a valuelist with Agency or Direct AgencyCB - This is a combobox from a query of the Agency Table DirectContactID - this will contain the Direct ContactID I would like to do the following... If the user selects Agency, in the AgencyDirectCB, then they must select an Agency from AgencyCB (it can not be null) and The DIrectContactID must be null, or not enabled,,,, (but what if there was already a contact in there, and user is changing from Direct to Agency, it would need it to be nulled out) If the User select Direct, then the AgencyCB must be null and DirectContactID must not be null Does anyone know how I would do this,, or have a similar example they could send me,, thanks so much -- Nancy |

Hi Nurse Nancy,
Here are some sample codes - air code, untested. Private Sub Form_BeforeUpdate(Cancel As Integer) If Len(Me.AgencyDiretCB) 0 Then If IsNull(Me.AgencyCB) Then Cancel = True MsgBox "You must select an agency" End If End If End Sub Private Sub AgencyDirectCB_AfterUpdate() If Len(Me.AgencyDirectCB) 0 Then Me.DIrectContactID = Null End If End Sub Jeanette Cunningham MS Access MVP -- Melbourne Victoria Australia "Nurse Nancy" wrote in message ...
