Makro i excel

Application.ScreenUpdating = False

'din kode'

Application.ScreenUpdating = True

Hvad hvis denne kode ikke er i min makro?
- hvor skal den så indsættes?

Den ser sådan her ud:

Sheets("Del3 - Behov").Select
    Sheets("Del3 - Beregning").Visible = True
    Sheets("Del3 - Beregning").Select
    ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True
    Sheets("Del3 - Beregning").Select
    ActiveSheet.Unprotect
    SolverReset
    SolverOk SetCell:="$D$39", MaxMinVal:=2, ValueOf:=0, ByChange:="$D$30:$J$30", _
        Engine:=2, EngineDesc:="Simplex LP"
    SolverAdd CellRef:="$D$30:$J$30", Relation:=4, FormulaText:="heltal"
