The value in the Array at index 14 is ' +"<br />"+"<br />" '. Adding + before a String form value , is converted to a Number . so it's converted equaling is "Not convertible to valid number ", so it saving as NaN -Not a Number ". that's why returning NaN.
Remove + before it.

In this case you use a prompt. Then you use the answer from the promt which is a string. Convert the string to a number and then you can use it.
