Trying to build new class, please help

[8thavenger]

Working in the SRD 3.5 game, I'm trying to add the spell less
ranger from the complete warrior. I've started with a copy of the ranger
class and it works for the most part but I can't add a favored enemy. It
does work if I add a level of the standard ranger so I'm assuming that
somewhere there is a check to see if the character has Ranger Levels. I
can 't find that code. I've included a copy of the data file. can you
please tell me what I'm doing wrong and point me to the documentation
where this is described? I seem to be unable to find it.
