Hi,

  1. When you compare 2 values in python, you have to write == instead of = .
  2. You have to indent your code.

I’m not sure this is the better way to save/load properties (you could use globalDict for example) but:

EDIT: You can also have a look at the errors messages in the console to see what’s wrong

thx a lot:)
