[Limdep Nlogit List] Lamda-values in bivariate

[rhythm Em]

Dear Limdep users,

I want to get two lamda-values (IMRs) after bivariate probit. I am strictly following the commands given in LIMDEP manual (Page: E21-21). I wonder, when I reached to MATRIX ;b1= b(1:k1) ; b2= b(k21:Kvar), It shows error 399: check Syntax. first or last is bad  and Error 32. I carefully checked many times but not getting help. I could not exactly figure out meaning of all the syntax---about what they doing and how LIMDEP is dealing with Matrix language. Would you please help me to get my lamdas. I would appreciate your help. 

Thanks,
Rhythm
