When do you want it to happen
Say when the form is first shown
In the userform module:
Private Sub Userform_Initialize()
me.Label1.Caption = Worksheets("Sheet2").Range("B9").Text
End Sub
If you wanted to link it to a cell then use a textbox. for Properties,
change the specialeffect property to flat and the backcolor to menu bar
and Locked to true
This will make it look pretty much like a label.
