I require a simple function to increase an integer by +1 on every trigger (a=a+1). This so I can use a wireless remote as a controller to jump to markers on a sequencer. The sequencer will trigger videos and camera movements.

Richard was helping me with this and cooked up a compound using collections, however on my machine it does not seem to work. 

Any suggestions from Aximmetry on how to tackle this? Is there documentation on collections and do they work with my license? Or, is there a better way to achieve this? 

I have a DE Professional license.

Thank you
