Need help with my script

Hello all,

I attended the workshop back in March, and am trying to estimate a longitudinal model. I have been working with the script provided at the training, but have modified it slightly because I am not interested looking at sex effects at this point. When I run the script, it appears as though it is running but when I look at the fit statistics this is what I get: EP = 0, -2LL = , df = 0, AIC = .

Could someone please take a look at my script and see where I have gone wrong? Thanks for any help!
