How to use array elements as transition condition in stateflow

I have a vector input to stateflow chart a =[1 4 1 3 3 2 1 4 1] In first state I am defining i=0 Initially in first state i is incremented by 1,there are two transitions for other two states. In first transition condition: [a[i]==1] for second [a[i]==2].The second condition is true and third condition is false so the transition occurs to second state. The problem is the transition stops in first state itself.any syntax error?

Could you share the screenshot of chart or the model itself.
