I feel like I'm using you guys being that I always ask questions but haven't yet had the ability to contribute a solution.

I currently have a SheetSet with all kinds of referencing fields in each sheet.  I have a little bit of an issue when it comes to customizing fields with Diesel.  I have a field stating what the current sheet number is on each sheet (this is edited in the SheetSet dialogue box, NO PROBLEM! .  I do, however, have a Title Sheet with a sheet number of "00".  I also want a field listing "sheet 01 of 22".  The "01" portion needs to be a field that takes the current sheet number and adds "1".  It sounds easy enough to me but  after hours of doodling and googling, all I ever get is "Invalid field code."

Thanks for the help!

See, you're contributing. 

Seriously though, don't worry about "using us". We're all just volunteering here. If we really felt like we were being used, I don't think we would be here very long.

Glad you got it worked out...and thank you very much for letting us know that you did. So many people have just posted their issues and never once responded to the (potential) solution or let us know if they figured it out...so we are greatly appreciative to you for doing that much, because it (potentially) saves us tons of research time.
