@yupengfei There is limited support for variables in functions. The following is supported.

gt(val(total), 100)```

Use of variables in second argument is not yet supported. So the following won't work.
```eq(school, val(myschool))
gt(numFriends, val(fcount))```

I have filed an issue for the same.

@yupengfei: The support for value variables in functions is in master now.
