Hi Diana,
The sry (widgets) I was referring to are lines of Javascript that should be towards the end of your page.
(These are separate from the sever-side validations that need the session save paths sorting by your hosts); once that has been sorted, you just need to add the following Spry javascript code just before the closing </body> tag on your contactus.php page:
<script type="text/javascript">
<!--
var sprytextfield1 = new Spry.Widget.ValidationTextField("sprytextfield1", "none", {validateOn:["blur"]});
var sprytextfield2 = new Spry.Widget.ValidationTextField("sprytextfield2", "email", {validateOn:["blur"]});
var sprytextarea1 = new Spry.Widget.ValidationTextarea("sprytextarea1", {validateOn:["blur"]});
var sprytextfield3 = new Spry.Widget.ValidationTextField("sprytextfield3", "none", {validateOn:["blur"], minChars:<?php echo $WAGLOBAL_Captcha_Characters; ?>, maxChars:<?php echo $WAGLOBAL_Captcha_Characters; ?>});
//-->
</script>
Hope things are working out despite FatCow's peculiar response.
