I'm calculating a safety factor, this safety factor is a function I created. I enter the parameters and everything is fine, but when I open the map it appears completely white and the only error I find is the georeference because it seems that there's no georeference. When I click on it to chage it, it says: "Ilwis 38 - Encountered an improper argument" and it won't let me change it. Does someone know how to fix this? Thank you.
