I think my problem is easy to solve, but so far I couldn't find a solution. I have a Feature Dataset created with the Union tool in ModelBuilder and now try to sum up all values of one specific field (VSG_EINZEL->up to 150 fields) into a new field (VSG_ALL) automatically in ModelBuilder. My problem is, that the number of VSG_EINZEL-fields is rather high and varies so I can’t use a static field calculaion like:
VSG_ALL = VSG_EINZEL + VSG_EINZEL_1 + VSG_EINZEL_12
and so on.
I am very new in using Python.
