You need to use Edit page: BeforeProcess event to check the value of that field. If field value is not 0 then display a message on the page and return false to prevent page from being displayed.
Other considerations:

  • make sure this field is not editable directly
  • set default value of this field to 0
  • in BeforeAdd event set this field value to 1 i.e.

$values["MyField"]=1;
