I am trying to find cells only within a specific range such as b8:I164

The following works fine except it acts upon the whole spreadsheet and
changes cells (with my code) that I do not want changed

Cells.Find(What:=Range(myFind), After:=ActiveCell, LookIn:xlFormulas, _
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
MatchCase:=False).Activate

How do I limit the range that is searched?

Thanks

Bob
