Hello,  
  
I wrote this script :   
  
SsID = input ('Numero participant: ','s');   
[w, wrect]=Screen('OpenWindow', 0);  
[width, height]=Screen('WindowSize', w);   
  
items = {'lapin', 'souris', 'voiture', 'saumon', 'vélo', 'table', 'cochon'};  
Order=items(randi(length(items)):end)  
  
for i = Order   
 Screen(w, 'TextFont', 'Calibri')  
 Screen(w, 'TextSize', 50)  
 DrawFormattedText(w, items, 'center', 'center', [54,54,54])   
 Screen(w, 'Flip')  
 WaitSecs(2)   
end  
  
Screen('CloseAll');  
  
DrawFormettedText functions if I don't use the command 'items(randi(length(items)):end)'  
But with this one, I have this error message :  
  
??? Error using ==\> strfind  
Input strings must have one row.  
  
Error in ==\> DrawFormattedText at 136  
newlinepos = strfind(char(tstring), '\n');  
  
Error in ==\> EssaiRandint at 19  
 DrawFormattedText(w, items, 'center', 'center', [54,54,54])  
  
I have looked at forums, DrawFormetedTextdemo, etc, but without succes.  
I dont understand the error, and that would be very nice if somebody can help me.
