date compare not working

[Guest]

If DateDiff("d", Date - 1, Me![LaborDate]) = 0 Then
Me![Command1].Enabled = False
Me![Command1].Visible = False
Else
Me![Command1].Enabled = True
Me![Command1].Visible = True
End If

Date - 1 = yesterday, labordate=yesterday

But, the command button reamins visible and enabled. What
is the matter. Very Very frustrated!!!

Thanks

as in other post, try date()-1 rather than date-1
