Update Requests forms don't honor Column Type limitations
When sending an update request for say a ranking from 1-10. The column may have a restriction to only allow valid values but the Update Request Form will allow anything, even text. This breaks the first rule of good data GIGO and requires us to spend time not only cleaning bad data, but chasing back after the person who received the update request.
You often only get one chance getting data back from people. If they have to re-do their answers they will give up or worse enter misleading information.
