The Score column must be defined with cNumbers.
The CSV file doesn't save the columns types (unlike the XML format).
So when you load a CSV file and ask it to create the columns it assumes that all columns are string columns.
The solution is to first create the columns and then load the CSV file without create new columns (specci48 solution).
Another option is to save the data as XML.
Thanks for the explanation Erel, I've never used XML before and so that's why I opted for CSV. Now that I understand the difference I think I'll try using XML as this will allow me to keep all the table control together in the corresponding sub. It's just a little more elegant that way.
Thanks once again for all the assistance.
