Removing ability to delete comments in excel

I want to use comments in a spreadsheet to record changes to values in a variety of cells so am looking to remove the ability to delete any comments, so that the history of the changes remain. I've gone on line and searched and found the following code:

Sub nocomments() 
    CommandBars("Worksheet Menu Bar").Controls("Insert").Controls("Comment").Enabled = False 
    CommandBars("Worksheet Menu Bar").Controls("Edit").Controls("Clear").Controls("Comments").Enabled = False 
End Sub

which then became

CommandBars("Cell").Controls("Edit Comment").Enabled = False 
CommandBars("Cell").Controls("Delete Comment").Enabled = False

so I thought I could just remove the first line of the code, but this isn't working. I'm getting the following error:

[FONT=&quot]Can't execute code in break mode

then its - Invalid outside parameter.

I'm not skilled enough to know how to sort so Can what I want be done and if so - what is the code required. Thanks[/FONT]

[QUOTE=skywriter;772594]Check out this thread.

Thanks Bruce. I went and copied the code in Thread #9 and attached the code to the sheet I was wanting it actioned in. Ran the Macro and it didn't make any difference. I was still able to delete a comment.

I don't know if I'm missing something here or my lack of VB knowledge is creating a hurdle here.......

Cheers
