Worksheet_Change Event does not execute upon change of cell

Good Morning, Tsjallie

Sorry, the misunderstanding was mine. I didn't get iso.

Here is the code I have now.

Private Sub Worksheet_Change(ByVal Target As Range)

Application.ScreenUpdating = False
Application.EnableEvents = False

Worksheet("PPW").Range("E9") = A
Worksheet("PPW").Range("E9") = B
Worksheet("PPW").Range("E9") = C
Worksheet("PPW").Range("E9") = D
Worksheet("PPW").Range("E9") = E

Call Update_PPW_GPMPct

Call Filter_Details

Application.ScreenUpdating = True
Application.EnableEvents = True

End Sub

I may have two problems.
1. Of course, the code does not run.
2. There are many cells in this worksheet that change. How can I make sure only cell E9 runs the code?

Thanks for your generous time and assistance.
