hi,<br><br>To start with, the MagicNumber variable needs to be a regular global variable that is declared in the global User Script section:<br><br>Dim MagicNumber as Integer<br><br>You implement such a variable as a eprime attribute because its value depend on the running context.<br>
<br>Eprime will automatically set the variable to 0 when it is declared, so you might have to initialise it at the start of the experiment (using an inline script object):<br><br>MagicNumber = 1<br><br>Then, instead of trying to increment the attribute value (which was
implemented incorrectly, BTW), you can increment the global variable like this:<br><br>MagicNumber = MagicNumber + 1<br><br>And finally:<br><br><p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">If
CInt(c.GetAttrib("Sentencenumber")) < Magicnumber then</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"><span> </span>Goto Skip</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">End if</p>
<br>Without quotes around the variable!<br><br>That's it.<br><br>best<br>Paul<br><br><div class="gmail_quote">On 2 February 2013 00:38, Tronix <span dir="ltr"><<a href="mailto:claire.zedelius@gmail.com" target="_blank">claire.zedelius@gmail.com</a>></span> wrote:<br>

<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">Hi!</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">I’m running
into some problems programming an experiment switching randomly between 2
lists. I want to present a text, displayed sentence by sentence, that contains
abnormalities in some, randomly selected sentences. For this, I created a
program that switches randomly between two nested lists. One list contains
regular sentences (e.g., “The tree grew.”), the other slightly modified
versions of the same sentences (e.g., “The tree gfrwr.”). Now I don’t want to
show any sentence in both the regular and abnormal version. To achieve this, I
numbered the sentences and basically tried to tell e-prime to skip a sentence
if a sentence with the same number from the other list has already been presented.
When I run the program, however, it seems to skip all the sentences. I can’t
seem to find the mistake. I’d be very happy if somebody here could help me with
this. </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">Here is what
I did: </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">1. I created
a variable (“Magicnumber “) that’s supposed to keep count of the presented
trials. In the beginning of the script, I set the value to 1:</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">c.SetAttrib
"Magicnumber", 1</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">2. To update
this value, immediately after the sentence display object I put an inline object
saying: </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">c.SetAttrib
"Magicnumber" , "Magicnumber" + 1</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">3. In each
of the nested lists containing the sentences, I created a variable (“Sentencenumber”)
containing the numbers 1 to 30 (from first to last sentence). </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">4. I inserted
a label object (“Skip”) a bit after the sentence display object. </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">5. In order
to skip sentences with sentence numbers already selected from the other list, immediately
before the sentence display object I inserted an inline object saying: </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">If
c.GetAttrib("Sentencenumber") < "Magicnumber" then</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"><span> </span>Goto Skip</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">End if</p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt"> </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">Does anybody
see what I did wrong here? </p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt">Thanks in
advance for your help!</p><span class="HOEnZb"><font color="#888888">
