>I tried what you suggested but couldn't get the SP code to fire when I did the tableupdate command. I think the validation rule will only fire if the field value changes. Right? But I need to change the datetime field no matter which field changes in the view and assumed the table update trigger would do it. I think I'l have to put rules in for every field that then changes the datetime field. Does this sound correct to you?

If you're buffering the table as well, you'll have to tableupdate the table after tableupdating the form. When you tableupdate the table the rule should fire.
