Can someone explain to me how the Environ () works. I saw it been used in
another example code here as follows:

Private Sub Workbook_Open ()
Dim myB as Workbook
If Environ("COMPUTERNAME") = "janphi" Then

I tried to use the same concept for my code:

If Environ("COMPUTERNAME") = "Work_Laptop" Then
Else
InputForm1.Show
End If

but the InputForm1 still come up. I want InputForm1 to only load when
someone else opens the file but when I open the file from my computer, I
don't want it to open. That is what I am trying to accomplish.
Any ideas?
