Parameter - Set default values - Some fields missing

Please help. I'm using Crytal Reports v.9. I would like to create a parameter and want to set default values. The table I'm using contains 150 fields, however, the Browse Field drop down only shows 22 fields. Is there a way to fix this so that it'll show all 150 fields?

Thanks a lot to all who respond!

Why do you want to set default value to 150 columns?
