Hi People,

Heres my prob:

I have a textarea. the user must input two of three answers, but one of the answers must be included to score a point. So it must work like this:

Answer Score
A 0 without B, 1 with B
B 1 with A or B (0 without A or B)
C 0 without B, 1 with B

So you need B+A or B+C, nothing else will give you a point.
Heeeeeeeeeeelp!!!!!!

Why don't you use checkboxes? I don't see how this can be done with a textarea.

Check two out of three:<br>
<input type=checkbox id=cb1> A<br>
<input type=checkbox id=cb2> B<br>
<input type=checkbox id=cb3> C<br>
<input type=button value="check" onclick=alert(checkAnswers())>

<script type=text/javascript language=javascript>
var cb1=document.getElementById('cb1');
var cb2=document.getElementById('cb2');
var cb3=document.getElementById('cb3');
function checkAnswers()
{
 if(cb1.checked=true && cb2.checked=true)return "GOOD";
 else if(cb2.checked=true && cb3.checked=true)return "GOOD";
 else return "BAD";
}

</script>

HTH,

Thanks snib thats great, but I am getting a syntax error, don't mean to moan, but I can't find it!

Hi Interrupt,

checked=true should be checked == true

Cheers,

Chris

Sorry..... should be:

Check two out of three:<br>
<input type=checkbox id=cb1> A<br>
<input type=checkbox id=cb2> B<br>
<input type=checkbox id=cb3> C<br>
<input type=button value="check" onclick=alert(checkAnswers())>

<script type=text/javascript language=javascript>
var cb1=document.getElementById('cb1');
var cb2=document.getElementById('cb2');
var cb3=document.getElementById('cb3');
function checkAnswers()
{
 if(cb1.checked==true && cb2.checked==true)return "GOOD";
 else if(cb2.checked==true && cb3.checked==true)return "GOOD";
