Macro Error

[A.S.]

Hello,
The macro below used to work in excel, however, for some reason it now
gives me an error. The error reads:

Compile error: Named argument not found.
The Macro is as follows:
Sub First_Macro_Rate_Sheet_Comparison()
'
' First_Macro_Rate_Sheet_Comparison Macro
'
'

'
Cells.Replace What:="Cell", Replacement:=" - Cellular", LookAt:=xlPart, _
SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
ReplaceFormat:=False
Cells.Replace What:=" - Cellularular", Replacement:=" - Cellular",
LookAt:= _
xlPart, SearchOrder:=xlByRows, MatchCase:=False,
SearchFormat:=False, _
ReplaceFormat:=False
Cells.Replace What:="Mobile", Replacement:=" - Cellular",
LookAt:=xlPart, _
SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
ReplaceFormat:=False
End Sub


Can anyone please help me in figuring out how to solve this error? The
program shows an error at SearchFormat, any ideas?

Thanks,
A.S.
