False Counter

Hi all,

I have a quelea system running with an eat behaviour, and every time an agent is eaten it briefly flashes 'false'.  My main inquiry is is there a way to create a counter for each of the flashes of false?  So that it tallies all the instances of 'false'?  The flashes are split amongst 20 different eating agents and I'd like to compile it into 1 singular increasing number 

Any help would be greatly appreciated

Thanks,

Davis
