Run Macro Unless Data Exists?

Right now, when selecting "Sheet2", this macro auto runs, and does it's thing. Is there a way to code it so that upon selecting sheet2, if data exists in the cells, make the macro go to the end of the list? For instance, this macro is great the first time someone goes to sheet2, but if they begin putting data in, and need to go back to sheet1 to reference something, then come back into sheet2, this macro runs again and moves the focus to the cell I coded. I need it to realize that there is now info in the cells, and move not to the selected cell, but to the end of the newly entered data.

Sub Macro3()
FinalRow = Cells(65536, 1).End(xlUp).Row
If Range("Manual").Value = True Then
Sheets("Usage").Activate
ActiveWindow.SmallScroll Down:=48
Range("A11").Select
Else 'assume Manual is false if it is not true above
Sheets("Usage").Activate
ActiveWindow.SmallScroll Down:=49
Range("A59").Select
End If
End Sub
