Selection.Offset(1, 0).Selec
Sheets("Engine").Selec
Range("D65510:g65536").Selec
Application.CutCopyMode = Fals
Selection.Cop
Sheets("Sheet1").Selec
Range("D65510").Selec
ActiveSheet.Past
Range("F65510:f65536").Selec
Application.CutCopyMode = Fals
Selection.Cop
Sheets("Summary").Selec
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks

Sheets("Sheet1").Selec

This workbook is updated weekly by adding additional sheets (Sheet1, (2), (3), etc). I don't want to manually rename each new sheet to update the workbook. The last sheet in the WB is named Caboose and it is needed (I think) for some SUM(Engine:Caboose) formulas

Thanks in advance for the help.
