I know that I have mentioned this before, but you have code that has "Form_" as a prefix. That is the way Access uses to know what the object is - you should never use that nomenclature.
Code:
Private Sub Form_Close() '<<-- Good - Required by Access
Form_frmProjectManagement.Requery '<<---BAD. You should never reference a form this way!!
End Sub
You have approximately 31 references in the code like this. These need to be fixed!!!
You have the button code in the form "sfrmTelework1" that is trying to requery two sub forms by using this code
Code:
Private Sub btnClose_Click()
Dim response
If (DCount("*", "tblTelework", "[PersonnelID] = [Forms]![frmPersonnel].[PersonnelID] AND [isActive] = true")) > 0 Then
response = MsgBox("Are you sure close Telework Contract?", vbYesNo, "Close ", 0, 0)
If response = 6 Then
Me.EndDate = Date
Me.isActive = No
Form_sfrmTelework1.Requery
Form_sfrmTelework.Requery
updateButtons
End If
End If
End Sub
I'm not saying this is the cause of the current error, but it will go a long way to fixing a lot of errors...
