Maybe this might help others:
We kinda solved problem #1 after talking to a python guy :-P
When you request values from http this MIGHT have some spaces included, even if you don't see them.
"So we put truncate spaces from both ends" an all those variabels and that works!
Don't think that this should be so hard to use - but anyhow - it works.
So #2 stays open. How to reveive 2 variables via http request
