Hi,I have four picture elements that randomly select an item from an item element. However, I noticed that sometimes an item is selected more than once, even though I used the "noreplace" attribute. How can I randomly select without replacement? This is the relevant part of the code:<item recallcues>
</item>

<trial fillrecallcues>
/ontrialbegin = [item.recallcues.item=item.poweritems1.1;
                 item.recallcues.item=item.indexitems2.1;
                 item.recallcues.item=item.fingeritems3.1;
                 item.recallcues.item=item.parallelitems4.1]
/ trialduration = 0
</trial>

<picture recallcue1>
/items = recallcues
/select = noreplace
/size = (20%,20%)
/ position = (10,10)
</picture>

<picture recallcue2>
/items = recallcues
/select = noreplace
/size = (20%,20%)
/ position = (30,10)
</picture>

<picture recallcue3>
/items = recallcues
/select = noreplace
/size = (20%,20%)
/ position = (50,10)
</picture>

<picture recallcue4>
/items = recallcues
/select = noreplace
/size = (20%,20%)
/ position = (70,10)
</picture>
Thanks,Diane
