	This should prevent the field from reclearing if they would like to edit it.

	formName - this is the name of the form you are checking, I would recommend using:  onsubmit="return checkForm(this.id);"
 	
	This function will only reject fields that have an * remaining as the last character.
	It also will reject incorrect emails in input fields with "Email" in their name (that are required).
	It WILL NOT reject blank fields, I would recommend putting CF Validation on process page for this feature.
