How would I fix these errors I get in JSBin?
JSBin
http://jsbin.com/ebizaj/edit#javascript,html
I get these errors.

1.Line 6: var name = prompt("What is your name?", ""); --- 'name' is already defined.
2.Line 12: var PromptAnswer = prompt("So, " + name + " do you play Soccer?", ""); --- 'PromptAnswer' is already defined.
3.Line 35: var PromptAnswer3 = prompt("Well, what sports do you like to play?", ""); --- 'PromptAnswer3' is already defined.

What should I do? If I were to try to call the variable PromptAnswer3, it would do nothing.

    When you use var before a variable name, you’re declaring it. You can only declare a given variable once within a scope, and in each of the three error messages, you’re doing var [variable name] more than once.

    You can reuse your variables later, without putting var in front of them each time. So, on line 6 of your script, simply remove the var – it’s repetitive, and not needed.

    Remove the duplicate var on each line mentioned in the each of the error messages, and you’re done.
