I actually seemed to have the same error if one of the ifs was comparing things between “”. If it was comparing other things like numbers and had the proper double parenthesis set up, it seemed to work fine.
I think that turning implicit control flow on solved that, as I’m not getting that error anymore (it’s been a long time since I tested it though); try using that and reverting to the one line before and see if it works?
Implicit control flow is off by default. To use it, you have to *create implicit_control_flow true in startup.txt.
