Macro to hide cells

[Moxioron]

Hello.

I have a macro that I want to use to hide cells. I have created macros to hides cells numerous times with no issue.

However, this time for some reason it's hiding an extra cell. I want it to hide cell C through M...and it's hiding B through M. Where am I going wrong? Thanks for your help.

Sub Monthly()

' Monthly Macro

Cells.Select
Selection.EntireRow.Hidden = False
Columns("C:M").Select
Selection.EntireColumn.Hidden = True
Range("A1").Select
End Sub

Works fine for me on a blank sheet.
Try it on a new spreadsheet.
