the checkout form name is:
CheckoutWizard_Cool_Default
I had the wrong form name to replace [Formref] with
there are still a could instances where [FormRef] is used, replace thiese with:
CheckoutWizard_Cool_Default
then do a find and replace for:
CheckoutWizard_NewFromBlank_Default
and replace it with:
CheckoutWizard_Cool_Default
so my example above should have been:
(WA_getSavedFormValue('CheckoutWizard_Cool_Default','Email_Address'))
