NBBC Callback Tags + CI

[eluser]nagata[/eluser]
Ok guys so here is my problem,
I got my forum, I need bbcode's for it.
I found a good system for BBcodes called "NBBC" feel free to google it,
So my problem is that there are Callback Tags,
They give ability to do function's.
Sadly when I tried to combine my CI code and this NBBC system
It just broke the code in half way...
So any help guys?

Ps. Also I am sorry I am asking so many questions and so often
I am just learning
