your code produces the result, as far as your formula is true however, I omitted the complex getElementById construction and used the usual prompt for input. Are you familiar with this built-in feature?

to tell the truth, no, I can't. I modified it a little. so it will probably not suit you fully. but I can point out some errors to you. do you know how to use the coding platform that is located here?

your first mistake is in declaring variables. how does this happen? and Yes, place your code in the "codes {}" section. select this option, click the plus sign, select web, and drop your code there
