for the from address, you used the validated entries collection.
the validated entries collection is used by server validation and will only have a value if the form fails validation.
in the bindings panel, there will b a collection for the form, you should use the form binding group instead of the validated entries group.
NOTE: some hosts will not send an email if the from address is not a valid email address for your domain. to work around this, set the from address to a valid email address. in the universal email behavior, click the from button to access advanced from settings, you can use the form binding for the reply to address.
