Cant make AI follow Taxi path

[Meyham]

Hi,

I cannot make an AI plane follow a taxi path and take off.. I have done this before but a while back. and its always worked. I may have forgotten something I really dont know. I have spent 2 hrs on this and nothing I do works.. the ai plane starts its engine then just takes off in the direction it was pointed at ..  I have always just made them take off and not worry about a taxi path. but now that I try it doesn't work.. what tells the ai to follow a taxi path vs just taking off and ignoring one ? here is a screen shot of my little test session . 

Thank You

UPDATE :: I figured out what it was . I was using the fakefield_mwspawn .. for some reason it wont work for taxi paths need to use the fakefield instead
