Using B4xEval in B4i, I am getting the error : Target is null. Method called: Initialize
in sub Evaluate(Expression As String) on the line Nodes.Initialize

Any ideas?

I tried it in a new project with just B4xEval and discovered it was due to not initializing the B4xEval object itself. The location of the error threw me.
