Thanks for the replies everyone, makes sense. The bracket problem I meant to mention - when I previewed the post the brackets weren't coming out, so i put parentheses in.

To get some more clarification - do I need to be running -T for this to work? I was hoping I could just pass all my parameters through it and get a "this data is OK" or "not OK".
