Just first record of the form (data sheet view) will be updated by code

[masoud_sedighy]

In the form (data sheet view) I have, I put a click event for each field in the form like below, now problem is value of selected record of form will not be updated and just first record will be updated.
For example I have used below code for updating value of field of selected record ,for example value if (Item_Name="test1) and I want to change to "test2" and used below code but It cannot change value , just goes to first record, and value of first record changes.
I can manually change value of each field but by code no? Just first record changes.

Dim ct As Control
    Dim Cnt As Long, Rws As Long
    Dim Pos1 As Long, Pos2 As Long
   
    Pos1 = Me.Recordset.AbsolutePosition
   
    Set ct = ActiveControl
   
   
    ' Clear other selections if Ctrl or Shift key
    ' is not simultaneously pressed.
 
   If CtrlPressed = 0 And ShiftPressed = 0 Then
        P_ClearSelections
        Me.Recordset.AbsolutePosition = Pos1
      
      
       
        MsgBox Me.Item_Name -----(returned value is "test1")
        Me.Item_Name = "test2"
        MsgBox Me.Item_Name-----(returned value is "test1")
 
      
       
       
       
        ct.SetFocus
        GoTo ExitPoint
    End If

Complete code:

Private Sub Item_Name_Click()
P_Click
End Sub

Private Sub P_Click()
    On Error Resume Next
    Dim ct As Control
    Dim Cnt As Long, Rws As Long
    Dim Pos1 As Long, Pos2 As Long
   
    Pos1 = Me.Recordset.AbsolutePosition
   
    Set ct = ActiveControl
   
   
    ' Clear other selections if Ctrl or Shift key
    ' is not simultaneously pressed.
    If CtrlPressed = 0 And ShiftPressed = 0 Then
        P_ClearSelections
        Me.Recordset.AbsolutePosition = Pos1
      
      
       
        Me.IsSelected = True
        MsgBox Me.Item_Name
        Me.Item_Name = "support"
        MsgBox Me.Item_Name
      
       
       
       
        ct.SetFocus
        GoTo ExitPoint
    End If
   
    If ShiftPressed > 0 Then
        Rws = Me.SelHeight
        If Rws > 1 Then
            Pos2 = Me.SelTop - 1
            For Cnt = Pos2 To Pos2 + Rws - 1
                Me.Recordset.AbsolutePosition = Cnt
                Me.IsSelected = True
            Next
        End If
        GoTo ExitPoint
    End If
   
    Me.IsSelected = True
   
ExitPoint:
    ' Save the status
    Me.Dirty = False
    ' Update display in SF_Selected
    Me.Parent("SF_Selected").Requery
   
    ActiveControl.SelLength = 0
   
    Set ct = Nothing
    On Error GoTo 0
End Sub
