All I want to do is to make sure every time there is a change in the combobox
all cells are updated, but it doesn't so I tried forcing it byreplacing and
equal sign by an equal sign something like this:

Sub UpdateWkbk()

Dim sht As Worksheet
Dim dashsht As Worksheet

Application.ScreenUpdating = False
Set dashsht = Worksheets("Dashboard")
Set sht = Worksheets("Data")
sht.Select
alreadyupdate = True
For i = 1 To 10
sht.Range("J8:U40").Replace What:="=", Replacement:="=", LookAt:=xlPart, _
       SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
       ReplaceFormat:=False
       alreadyupdate = True
       Application.Volatile
Application.SendKeys ("%XR") ' This is to execute a refresh of a UDF because
is also not happening automatically.
Next i
dashsht.Select
Application.ScreenUpdating = True

End Sub
However, this triggers the Combobox

So I figure I work around it like this:

Private Sub ComboBox1_Change()
      If alreadyupdated Then
     Exit Sub
Else
   UpdateWkbk
End If
   alreadyupdate = True

End Sub

Nothing is working
I have ensured that in my options, I have set my calculation to automatic
Calculation.
