Hi Brenda,
For many of the fields you have the same onBlur server error ID (nameServerError), so they will all display similarly if the 'name' field doesn't validate.
I think the best bet would be to keep the original contactus.php fields and sections of code (both above the 'DOCTYPE' line and in the javascript widgets at the end) and clear the rest of the fields of any spry or error code - so it is just the input (type name id etc) left.
Make sure the form sends OK with just the name, email and comment fields requiring validation, then add the validations to your extra fields, either using the Server Validations from the WA Validation Toolkit (Server Behaviors > Click the 'Plus' Button > WA Validation Toolkit > Server Validations), or using the Dreamweaver Insert > Spry > Spry Validation X field.
Doing it this way will ensure that each field will be correctly identified for validationn.
