Your code format is wrong…

Ploblem Building My First Extention

Since you’re learning I have a suggestion. Instead of using an EventDispatcher I recommend: Replacing “void” with “int” or “double” and “GotResult” with “return” Something like this: @SimpleFunction(description = “Add two numbers”) public double Add(double num1, double num2) { return num1+num2; }
