Can't use varien - magento

Question

In the template register.phtml I added an input type radio for some terms and condition agreements.
This one is required.
I didn't success to use the javascript Magento’s frontend validation. I add all sort of classes but nothing worked.
Is Someone knows how to do please ? thanks
Here the html
<div class="field radiobox">
<div class="input-box">
<input type="radio" name="accept" title="<?php echo $this->__('I Agree to our Terms & Conditions') ?>" id="accept" class="radio required-entry validate-one-required-by-name validation-passed validation-failed" >
<label for="accept" class=required" ><?php echo $this->__('I Agree to our Terms & Conditions') ?></label>
</div>
</div>
<script type="text/javascript">
//<![CDATA[
new Varien.FileElement('accept');
//]]>
</script>

Answer 1

First of all remove all class other then required-entry
<input type="radio" name="accept" title="<?php echo $this->__('I Agree to our Terms & Conditions') ?>" id="accept" class="radio required-entry" >
And put this in your form tag, you don't need to create any javascript for this just ensure that it is under form tag, in register.phtml file magento already define validation javascript so don't put your javascript again.
