/* Submitting button needs ID, e.g: id="Submitter" (to avoid double submission) 
/* For checking e-mails validity use word 'mail' anywhere in the fieldname, e.g: 'email' or 'Mail3'
/* For checking numbers validity use word 'num' anywhere in the fieldname, e.g: 'num3' or 'AmountNum'
/* For checking any 2 fields confirmation match use any names in pairs as the 2nd array member
/* For NOT checking a field use the <DisabledChar> as the first letter of its name
