Try this, it appears you have a value of 10 questions but your quiz only has 7. make the following changes in your code and it should work.


var numQues = 7;
var numChoi = 4;

var answers = new Array(7);
answers[0] = "3";
answers[1] = "Compression";
answers[2] = "Direct injuries";
answers[3] = "400+";
answers[4] = "Cardiac muscle";
answers[5] = "30 Seconds";
answers[6] = "Above heart";


Let me know if all works out.

My pleasure, glad I could lend a hand! Sometimes it is easier to find the little things with fresh eyes. I am sure after a good nights sleep it would have jumped out at you.

Have a good one!

You up for another problem? Heres hoping...

The score is all messed up, no matter what happens the % of the correct unswers is really low. Unrealisticly low.

Anybody?

A Train,

If you look at your code, where you list the questions/answers, your values are not matching. Thus the script does not recognize the correct check mark cause the value of the answer does not match:

1. How many different <b>types</b> of muscles does your body have?<br>
<input type="radio" name="q1" value="1">1 <br>These are Correct
<input type="radio" name="q1" value="2">2<br>
<input type="radio" name="q1" value="3">3<br>
<input type="radio" name="q1" value="4">4<br>
<p>

2. What does 'C' stand for in RICE?
<br>
<input type="radio" name="q2" value="Low Frequency Wave">Contact<br>These do not match
<input type="radio" name="q2" value="Transverse Wave">Consume<br>
<input type="radio" name="q2" value="High Frequency Wave">Compression<br>
<input type="radio" name="q2" value="Longitudinal wave "> Cartilage<br>
<p>


Just go through your questions/answers and correct the values and all should work fine.
