This is a quoting problem - single-quotes are not interpolated.

That means:  the argument (to the screen command) that is in '...' will not
be scanned by the shell (script) for variables (etc) - and will appear
empty in this case (since $zahl is not in your environment, perhaps).

You need to do something like the following (to get the variable back out
of the quoting, so that it will be interpolated):

        screen -p $zahl -X eval 'stuff ./run_node.sh" '$zahl' \015"'

or, for more general such scenarios, a more bullet-proof version would be:

        screen -p $zahl -X eval 'stuff ./run_node.sh" '"$zahl"' \015"'
