At first, I was not able to reproduce the error, but then I realised that you probably don't save the content of lower left and right parts (`@.Statements).Use cmd+s to save changes. The error is raised because parser tries to parse the old code (same as in upper left part) with a method intended for rewrite rules. That should fix it. If you have any other questions related to RewriteTool don't hesitate to ask.
