in the source code i see the following:
<div id="SimpleContact_NewFromBlank_Defa<link href="SpryAssets/SpryValidationTextField.css" rel="stylesheet" type="text/css">
this should be:
<div id="SimpleContact_NewFromBlank_Default"><link href="SpryAssets/SpryValidationTextField.css" rel="stylesheet" type="text/css">
cant say why that is happening, just that it is.
