I have tried everything but the array stubbornly refuses to populate
any sheet except the one the code belongs to:

Sub WontChangeWorksheetDestination()

Dim wks As Worksheet
Set wks = Sheets(3)

With wks

Set TheRange = Range(Cells(1, 1), Cells(10, 10))

TheRange.Value = MyArray

End With

End sub

I've tried everything, but because the code is behind a button on
sheet 1 the array populates sheet 1 and doesn't seem to want to
populate any toher sheet no mattwer hw I try to qualify it ... what am
I missing?

Any help gratefully accepted,

Kind regards, Mark
