.I'm not getting the correct answers. My goal is to remove the button and just do the calculation when the 2nd or 3rd spinner item is selected.. I think my problem maybe with the spinner listeners but im not sure(not getting any errors just not getting the correct answers, I know the conversion functions are correct).....
My code is not complete, just not working correctly so far
- Code: Select all
