Code not running correctly

Hello! I am running into some problems with my code. Im trying to have the code restart if they did not meet a certain criteria. However, the code right now is just ending after the designated number of trials 50. 


Can anyone tell me where I am going wrong in my code?

options
mouse on # mouse is being used, so do not hide it
bitmapdir stimuli # location of the bitmaps
sounddir stimuli # location of sound files
escape # you can escape by holding escape until end of trial

bitmaps
circle1blue # this refers to bitmaps/circle1blue.png
circle1green # etc.
circle1red # each card is 100x100px
circle1yellow # you can change this, of course, making
circle2blue # changes to the SVG file
