Having trouble with If Then command:

[dbeck114]

Ok I've been working on this now for several hours and am still having some issues. Maybe I just need to simplify this by breaking it down into two steps. Here is what I now have.

Module Module1
 
    Sub Main()
        Console.WriteLine("please enter a number between 1 and 9, or one of the following letters a, b or c")
        'here is where I would like the program to determine if the input is a number or a letter
        'unfortunatly my text book in on program structure and not on VB so no useable code is 
        'in the book.  
        Dim input = Console.ReadLine()
        If input <= 1 OrElse >= 9 Then
        Else input <> (a,b,c) then
            Console.WriteLine("Im sorry, but you did not enter one of the designated characters.  Please try again")
 
 
        End If
 
 
    End Sub
 
    
End Module
