Hi Marco
Those error messages can be a little uniformative sometimes! Not sure what
is causing your problem as I am still trying to understand the different
variable type descriptions used in batch mode, but there seems like an
inconsistency in your code where extra curly brackets (i.e.'{') might be
required since you are specifying a series? (see '*' below).

and maybe here as well?

hope this helps
