Getting an AI blackop to Shine his Laser on a Tank

[C0LDSt33L]

In a mission I want to make this guy point his laser at a tank and fire at it so a laser dot is visable. In the trigger field is

Code: [Select]

leon dotarget tank; leon fire "LaserDesignator"; leon dofire tank
He takes the designator out and points it at the tank but there is no laserdot on the tank. I've also tried:

leon fire ["LaserDesignator","LaserDesignator"]

and

leon fire ["LaserDesignator","LaserDot"]

Where am I going wrong?
