I always get into a trouble when referring to a range via an inputbox and a
Cancel button is clicked or it is left Blank. Any suggestions?

Furthermore, what might be wrong with the following code?

Sub CHECK()

Dim FIRST, SECOND, THIRD As Range

Set FIRST = Application.InputBox("FIRST!", , , , , , , 8)
If FIRST.Address = "" Then
Exit Sub
MsgBox "--:" & FIRST.Address & ":--"
End If

Set SECOND = Application.InputBox("SECOND!", , , , , , , 8)
If SECOND.Address = "" Then
Exit Sub
MsgBox "--:" & SECOND.Address & ":--"
End If

Set THIRD = Application.InputBox("THIRD", , , , , , , 8)
If THIRD.Address = "" Then
Exit Sub
MsgBox "--:" & THIRD.Address & ":--"
End If

End Sub
