Unsupported Compare Operator



I am playing CodeCombat since several days and now at level 19.
I am getting stuck when I want to use +, - , *, /, ==, >, <, >=, <=, +=, -= etc.
The code is running into error. The displayed error is the following in the uploaded image.

Could anyone have a look and advise? Thanks so much!

Best regards,


The code in the screenshot you have posted seems fine. Can you copy your whole code and post it here? Then the readers will be able to try and debug it properly.
