FiRST Year Team - need Timer HeLP

[Cobra]

hey guys. Well heh, im havin trouble settin up the timer on my bot. the motor is supposed to go 36 cycles/s so in the code we are using this for a timer...

if a_count = (36 *4) then y
y:
drive_R=220

a_count = a_count+1


if i can get the counter to pause for 3 seconds and do the drive_r action the 4th second, that would be all the help i need for now.The code is in the main loop, and all i want it to do is obey the timer... ill be waitin for your replies..ty
