Ok I fixed the 10 & {{ but I still don't understand how to get second part ("red") to show in the final document. "Hellow world" will display but not "red". This may seem silly but I plan on doing a lot more and this is a learning process for me as the docs arnt very clear. Please explain why you say handle() is only executed rarely. The instructions say that this is where all the processing should be done or did I mis understand. Perhaps fix my little script so I can see what is wrong?
