Ok lemme see if I got this right,
you need help getting the NP on hand and getting the auth down?
Not sure what language you're using, I'm going to assume VB6. Auth information will be posted later. For NP on hand, look at the source and look for where the NP is displayed:
is what it looks like. What you want to get is the 30, so you'll just want to use a GSB function. What might be getting you is the quotes though.
