Need help with Form Control Check Boxes Please

TEST ON A SAMPLE OR COPY OF YOUR WORKBOOK

I would add the checkboxes like this for the range I needed them. And make the the checkbox name = "Check box " & the row its in.

Sub test()
 Dim cb As CheckBox
 For ptr = 2 To 10
    Set rng = Cells(ptr, "k")
    Set cb = CheckBoxes.Add(rng.Left, rng.Top, rng.Width, rng.Height)
    With cb
        .Caption = "hello world"
        .Name = "Check box " & ptr
        '.OnAction = "Macro"
        '.Visible = False
    End With
 Next
End Sub

Then you could hide and unhide them by name. I dnt know the full scope of your project so this is just an idea.

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Range("j2:j10"), Target) Is Nothing Then
        If Target.Value > "" Then
            Shapes("Check box " & Target.Row).Visible = msoCTrue
        Else
            Shapes("Check box " & Target.Row).Visible = msoFalse
        End If
    End If
    Set rng = Nothing
End Sub
