Problem addressing subobject properties

[David McFarlane]

Katrin,

Neither Slides nor TextDisplays have a "Text1" property, they have a 
"Text" property, and that accounts for your error message -- see the 
Slide topic in the E-Basic Help facility.  So your lines should instead read

      Slide.Text = "..."

But if you had not made that mistake and then posted your question, I 
would not have the opportunity to correct you bigger mistake.  You 
really should not change object properties directly in code this way, 
for at least three reasons as I discuss at 
https://groups.google.com/d/topic/e-prime/g1Fv2CGaSeg/discussion .  As I 
explain there, you should instead use an attribute reference.  Add an 
attribute reference (e.g., [Text]) in your Slide or TextDisplay, and 
then your code might read

     If (c.GetAttrib("Question") = "1") Then
          c.SetAttrib "Text", "..."
     Else
          c.SetAttrib "Text", "..."
     End If

Or if you dare, do this all in a single Iif statement,

      c.SetAttrib "Text", Iif( (c.GetAttrib("Question") = "1"), _
         "True...", "False..." )

Stock reminder:  1) I do not work for PST.  2) PST's trained staff take 
any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they strive 
to respond to all requests in 24-48 hours -- this is pretty much their 
substitute for proper documentation, so make full use of it.  3) In 
addition, PST takes questions at their Facebook page 
(http://www.facebook.com/pages/Psychology-Software-Tools-Inc/241802160683 
), and offers several instructional videos there and on their YouTube 
channel (http://www.youtube.com/user/PSTNET ) (no Twitter feed yet, 
though).  4) If you do get an answer from PST staff, please extend the 
courtesy of posting their reply back here for the sake of others.
