My turn based battle system

Well im working on a turn based battle system for ym campaign aned i kinda have problems
I wont shwo you the map
btu here are the triggers ill descibe them

Ok nwo the battle starts all monsters and heroes are there , theyre paused etc
now we set the amount of the ATB (hwo much time si left until theyre turn)
for every monster and heroes a random amount is set between 0 and 65536
Then i launch a trigger that checks if any ATB is full (in case some one would have the luck ( a chance 1 from 65536) that he started with a full atb)
its for every hero or monster
if HeroATB1 >=65536 then
herogivingcommand (a unit variable)=hero1
run trigger shwo battle menu
Skipp all remaining actions

ok but thats ok
if nobody has a Full ATB it charges a trigger that increases the ATB by a certain amount
HeroATB1=HeroATB1+ (((Hero1 Agility + 20) * 96) / 16)

then after all the atbs are filled it runs the check ATB trigger again
and so on , but after the beggining amount is calculated all stops , the amount doesnt rise im sure of it (i have made the ATB gauges visible and it stops)

Can anyone help me????
