Trigger help: Counting Units

[Franklin 0]

I have a trigger set to figure out when a handful of groups are for the most part dead, and when some groups are entirely dead. I have searched the forums and found some examples of this, but none of the solutions are working for my particular scenario.

This is what i have in the condition field:

{!alive _x} count units qrf1 <= 1 && {!alive _x} count units qrf2 <= 1 && {!alive _x} count units qrf3 <= 1 && {!alive _x} count units qrf4 <= 1 && {!alive _x} count units qrf5 <= 1 && {!alive _x} count units qrf6 <= 1 && {!alive _x} count units drivergroup == 0 && {!alive _x} count units gunnergroup == 0;

I want to know when the QRF groups are equal to or less than 1, and when the driver and gunner groups are entirely dead. Then execute a script from the "on activation" field of the trigger.

Wouldn't it be better to count the alive units.

{!alive _x} count units qrf1 <= 1 will be true as soon as you start the game as no units are dead.
