[Limdep Nlogit List] Error 636

[Kalyan Chakraborty]

Dear Prof. Greene and other Limdep Users,

I have been trying to run a Dynamic Panel GMM model (ABB) E11.15 (Nlogit 9)
but getting the same error message no matter how I select my I-Variables. I
have 68 countries, 50-years of data, the program I reproduced below. Any
help is very much appreciated.
