Hi,
When using the blockfeedback function I am getting an extra percentage symbol when I run the experiment. 
My block looks like this
<block array>
/ trials = [1-3=noreplace(definite_stop, definite_pass, probable_stop, probable_pass, ambiguous_stop, ambiguous_pass)]
/ blockfeedback = (correct)
</block>
Any idea whats going on? A bug? My codes are wrong?
Thanks
