Compare Text Via Macro Code

I m trying to write some code use VBA in excel to look at cell C2 and if it equal A0 or whatever then it will put in cell D2 = "blah blah" and then go down to the next cell C3.

Select Case Range("C:C").Text
Case "A0"
Range("B1").Value = "not booked"
Case "A1"
Range("B1").Value = "Misplace documents"
Case "A2"
Range("B1").Value = "Closing cancelled"
Case Else
End
End Select
End Sub

I have a report that in one column codes (A1,A2,A3,B3 etc..) and these codes have a description and I want the VBA code to look at the description Code and then put in a different column the description. but Im having no luck.
