Run Time Error 94

[Vethra]

Hi everyone,



I'm sure this is simple for all of you guys but unfortunately I can't find a solution. Everything works great except one thing, run time error 94 "Invalid use of Null" when textbox value is deleted and the check box is still checked.

Private Sub Textbox1_Afterupdate()Checkbox1.Tag = Textbox1.Value
End Sub

Thank you,
Dilan

Shot in the dark, but try wrapping the textbox reference in the Nz() function.

Dead on shot, Paul...you must be using Night Vision Goggles! If the data in Textbox1 has been deleted, Dilan, the Control's Value is Null, and you cannot assign Null to a Tag Property as you're trying to do with

Checkbox1.Tag = Textbox1.Value

causing the Access Gnomes to complain with Error 94.

Private Sub Textbox1_AfterUpdate()
 Checkbox1.Tag = Nz(Me.Textbox1, "")
End Sub

assigns a Zero-Length String to Checkbox1.Tag if Textbox1 is empty, i.e. Null. You could replace the ZLS ("") with some other, appropriate String, if you wanted to.
