runtime error 2448 You can't assign a value to this object

[Liz_I3]

I am trying to assign a value on the ON OPEN of a form to a true/false control based on the value of another control

this is my code
Private Sub From_Open(Cancel as Integer)

If Me!

 = "04" then
Me![Verified] = true
end if

When I open the form I get a run time error 2448 You can't assing a value to this object.  Why?

I change my event from on open to on resize and it seem to work fine.

Is this the best place to put the code, so that as soon as the form is open on the screen to the user any code 04 would have the verified control checked as true all others would be false
