What I am not sure is you have commented all my codes which refer to the CGI queries and fields.

As all the words outside of code tags explain

Because that is the first step in fixing your program

The code as you have posted it cannot be debugged by anybody

Can you re-post your complete code which includes my queries as well or point to me in the right direction?

This is what I have attempted to do in Re: Output to a >CSV file

The "..." is where you fill in the blanks
