I have this macro which I pasted below and it works great. However once I
lock cells J7:116 and L7:116, the macro no longer works. Do you know what I
can do differently so that I can run the macro below but still keep cells
J7:116 and L7:116 locked?

Sub OrderThenFindEmptyCell()
Dim BlankCell As Range
With Range("B7:B11")
With .Validation
.Delete
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Operator:=xlBetween, Formula1:="=Order"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = ""
.ErrorTitle = ""
.InputMessage = ""
.ErrorMessage = ""
.ShowInput = True
.ShowError = True
End With
Set BlankCell = .Find("", After:=Range("B11"), SearchOrder:=xlByRows)
BlankCell.Select
End With
End Sub
