Hi Everyone,

I've got an input box that asks a question and I have the default set for
zero. I'd like to write some follow up logic that reverts back to the
beginning if the cancel button is chosen, but I'd like to keep the zero value
as true. Is there anyway to do this? I've included the code below. As always
I really appreciate the help.

Dim Sulfur As String
Sulfur = Application.InputBox("If you do not have any of this isotope in
your lab, please enter 0 and press OK", "35S", 0)
Range("G33") = Sulfur
If Sulfur = False Then
MsgBox "You clicked Cancel. Please try again.", 64, "Cancel was
clicked."
GoTo Sulfur
ElseIf Sulfur = 0 Then
GoTo P32
Else
GoTo P32
End If


Thanks,
Chad
