How do i read the toggles at my widget in secuence (if they are on and off) from the player controller blueprint?

Hello guys, im new to UE4,

I did a loop that is printing integer from 1 to 16 and then loop. i set a row of Toggles that i want to be read in order, one by one. when the toggle is being read i want it to change color or have any kind of signal that indicates where i am at the loop, read if its checked, and print if it is true.

please help me, here are the screenshots of my blue prints, however i just have the loop there.
