Med-Associates MedNR - lights not turning off when given command

Hi, been working on this program lately, the problem lies in state sets 5 and 7, when the button is pressed, the response is recorded and the the program appropriately proceeds to deliver a reward or initiate a timeout period, however the cue lights fail to turn off. Please let me know if you can at all help Thanks

\This is a visual discrimination task
\animals will simultaneously be presented with 2 cues, one a steady light, the other blinking
\animals will only be rewarded for pressing during the blinking cue.
\pressing during the steady cue will initiate a 15 second timeout cue
\ correct responses to a blinking cue will be scored as hits
\responses to a steady cue will be scored as misses

\constants
^house=7
^sweet=3
^LeftLight=4
^RightLight=6

\z pulses
\z1 dispense reward
\z2 max trails reached, ends program
\z5 cue selection(blinking or steady)
\z7 iti bin
\z8 right blinking light
\z9 left blinking light
\z12 timeout phase

\variables
\q=time marker to record latencies
\y=side selection
\b=blink counter1
\d=blink counter2
\u=timeout counter
\s= trial counter
