The problem is you are using <6 and checking every 30 seconds and you will always go to Retry layout because your score will always be below 6 in 30 second and will go to that layout without getting past that event.
The way to solve that is with a trigger variable.
Global Variable TRIGGER =0
SCORING >0 and SCORING <6 Set TRIGGER =1
SCORING >6 and SCORING <=8 Set TRIGGER =2
SCORING >8 and SCORING <12 Set TRIGGER =3
SCORING =12 Set TRIGGER =4
Every 30 Seconds
TRIGGER =1 Go To Layout Retry
TRIGGER =2 Go to Layout Average
TRIGGER =3 Go To Layout WINNERS
TRIGGER =4 Go To Layout Excellent
With that it only checks once at 30 seconds for you SCORING and the TRIGGER will send it to the correct layout
Remember to reset TRIGGER =0 when you go back to play or it will just keep sending you to that layout.
