When the security setting Secureforms is set to yes, the online assigments cannot be entered. No error is displayed, the input simply isn't recoreded. If secureforms is set to no then you can enter/edit online assignments, but when it is set back to yes, again you cannot edit/enter online assignments, but you can still view what you entered while secureforms was set to no.
