<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Hello LON-CAPA users,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">I generated few problems using Function Plot Response (Bode plots in Electric Circuits).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">I am having two issues that I am not able to resolve.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">1) One student (out of around 50!) cannot submit the curve:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">The student is getting a message “Not a Function”, after hitting the submit button no matter how the curve to be submitted looks.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">The issue does not depend on the browser used, nor on particular PC. We ‘ve tried this from another PC.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">The problems given to all students are mainly identical. Randomization does not involve anything related to the function plot.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">However just one out 50 is having this issue.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Any ideas why this might be happening?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">2) Whenever I try to manually grade or view submissions for the Function Plot problems, very often while opening the student problem page,
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">an error message pops-up :”GeoGebra Error. Redefinition Failed”. The only option is to hit OK.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">After that I can still see the submitted curve and computer graded results.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">But what triggers this message and can this error possibly lead to some errors in computer-graded Function Plot Response problems?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Any help is greatly appreciated.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Thank you,<o:p></o:p></span></p>
