Heres a demo.
In this case I am checking only the range of the second bin. The Inside range will show if the bin is the active input.
I am feeding 2 Bins into 1 movie player so that I could easily route the 2 inputs to one test.
The user actors 'DX int thru' are empty actors that just pass the Interger values thru (I use them to allow branching when needed).
So the 'inside' output of the INSIDE RANGE actor will tell us what bin is active. You can use this to output text or what ever you like.
