Action buttons on iPhone/iPad

I have a web-enabled Notes db that works fine on iNotes. The action buttons are not visible on the iPhone or iPad. Also an approval button with the code:

FIELD App1Date :=@Now; “”;

FIELD Approver1:=@Name([CN];@UserName);

FIELD Approved1:= “Approved”;

@Command([FileSave]);@Command([FileCloseWindow])

is not working either. The user sees the button but when clicks it, nothing happens. Will this only work with an XPages app?

Thank you for any input.
