You need to define Expression. Try adding var Expression = algebra.Expression.

saurabhvyas commented 8 years ago

Okay algebra.Expression solved the problem It would be great if can update the docs so other users dont face similar problem

nicolewhite commented 8 years ago

It is in the documentation. Thanks!
