Thank you so much! This solved the issue I was having, I just needed to delete the state_off row and the fourth else-if, and change all of the states that were in $Self to % Ignore% and the program ran flawlessly.
Help with State Transition Table

Greetings, I am diong a project where I am creating an air piano inside simulink with my arduino uno board. The table is for lighting three LED lights based on different distance inputs from an ultrasound sensor. The output I am currently getting is that only my green LED lights up despite inputting several different distances. any help or tips would be greatly appreciated. I have also included a picture of my blocks diagram in simulink.

But did you see @Fangjuns answer? The condition that you are using is still wrong.

The below example explains why you got the "correct" result after making the "wrong" changes.
After making the changes your described, please run a simulation where "distance" is fed with a Constant block with value 35. You will see the state stays at Green, which is obviously wrong.
You could attach your model for others to try.
distance=35;
[0<distance<10]

[0<distance<10] is not the correct syntax. Your state stays at the default.
changing all to style [0<distance && distance<10] should resolve the issue.

distance=35;
[0<distance<10]
This is equivalant to
(0<distance) < 10

yes, proper logical and should be used for stateflow conditions in the similar way done in MATLAB
