your code is working. However since you didn't give here your
definitions of von, I assume that somehow it has values that are not
changed into graphics primitives according to your replacement rules.
For example if you test your code with
von=Table[i,{i,-1,2},{4}]
it will work
but with
von=Table[i,{i,-1,3},{5}]
it will not, since for the value 3 there is no replacement rule
