Hello juan

I want to thank you first for your valuable job.

I’m trying to use fuzzylite for android application but unfortunately i get nan answer with all the inputs.

I’ve tried all your previous recommendations and I also compiled and executed my code but the same result again (nan).

I also kept my code structure with samples in package but it worked fine. I am really confused now.

Any help would be appreciated. Here is my code.

```
import com.fuzzylite.*;
import com.fuzzylite.defuzzifier.*;
import com.fuzzylite.factory.*;
import com.fuzzylite.hedge.*;
import com.fuzzylite.imex.*;
import com.fuzzylite.norm.*;
import com.fuzzylite.norm.s.*;
import com.fuzzylite.norm.t.*;
import com.fuzzylite.rule.*;
import com.fuzzylite.term.*;
import com.fuzzylite.variable.*;
