Task 8 issue

[jonfriskics]

In the task "Only set the "answer" and "attempt" hidden inputs when they aren't already set", it starts with:

"When we go to call the setHiddenFields functions in our guess function, we should only update our hidden inputs when they're not set."

Should that instead be something like:

"Call the setHiddenFields() function in the body of the guess() function, but also write some logic so that it's only called when answer and attempt haven't already been set."

Updated in both the .com and readme.md file.
