Multiple Image Responses

[ben robinson]

i'm a big fan of Select Case... rather than If Then... when things start
getting complicated.
you could do something like this:
Select Case strhit1
    Case "redcircle"
        Select Case strhit2
            Case "bluecircle"
                CORRECT
            Case Else
                INCORRECT
        End Select
    Case "bluecircle"
        Select Case strhit2
            Case "redcircle"
                CORRECT
            Case Else
                INCORRECT
        End Select
    Case "redsquare"
    Case "bluesquare"
End Select
