st: a invalid syntax Error

[Xavi Barber <xbarber@altern.org>]

Dears statalisters:

I'm working with logistic command everydar, and today Stata report a error 
and I'm confunding, I do not deal because this mistake goes out.


. xi: logistic esofago i.sexo1 if filter==1
i.sexo1           _Isexo1_1-2         (naturally coded; _Isexo1_1 omitted)
invalid syntax
r(198);


Sexo1 is a (0,1) variable -->Sex  Male/Female
esofago is a (0,1) variable --> esophageal cancer Yes/No

Why today me it does not work?



I suppose that I will be doing something badly but I do not see it

Thanks
