Paul, we need to improve your question asking skills a bit.  :)

It's hard for us to help when we have to read through a lot of prose  
and even more code to understand the issue you are facing.  You'll get  
a lot better responses, and quicker, if you try to simplify your  
questions down for us.  "Here are the five lines I'm trying to use to  
delete a column of CSV.  Can you tell me why it's failing?" for example.

Basically though, the steps are almost identical to what I gave you in  
this message:

Just copy the data, leaving out the column you don't want.

I hope that helps.
