[SOLVED] form validation

[adam291086]

I need a tutorial or example code to help me hide form feilds. For example

 

If question 1 == No then keep question Two hidden. If question 2 ==Yes then show question two.

 

Thanks for the help

<script language="javascript">
function checker(val)
{
if (val == "Yes")
{
document.getElementById('negative').checked = false;
document.getElementById('question2').style.display='block';
}
else if (val == "No")
{
document.getElementById('positive').checked = false;
document.getElementById('question2').style.display='none';
}
}
</script>

Is this the first question you have ever answered?<br><br>

<input type="radio" onclick="checker(this.value)" id="positive" value="Yes">Yes
<input type="radio" onclick="checker(this.value)" id="negative" value="No">No

<br><br>

<span id="question2" style="display:none">
Add your second question here.........
</span>
