I'm not sure if I completely understand your question since I do not know German, but if you are looking to run the A5 template:
You must define "ENTITY1" when you want to use A5 templates in A7 or A8. Add something like "define ENTITY1 skill99;" in your script before you include the templates.
Alternatively, you may download my adventure template, which has similar functionality to the A5 template and was designed for A7 and A8, for free at my website

Hope That Helps,
