Global variable script problem: type mismatch

[liwenna]

Ow and for the second question...

----------------------------------------------
If InputSlide.RESP = "1" Then
     Feedback1.Run c
If InputSlide.RESP = "4" Then
     Feedback2.Run c
Else
     Feedback3.run c
End If
----------------------------------------------

Of there's only two allowable inputs (1 and 4) then a non-response
should automatically sort under 'Else' and show the third
feedbackslide. Alternatively you could try

If InputSlide.RESP = "" Then
     Feedback3.run c

but not entirely sure whether that will work.

Again, no e-prime at hand so not sure if it works, but I think it
should.

Best regards,

liwenna
