My fire effect

Hello, I was wondering if there was something wrong with this code:

function pskProjectile::onCollision( %ourObject, %theirObject, %ourRef, %theirRef, %time, %normal, %contacts, %points )
{
    // Trigger Impact?
    if ( !%ourObject.triggerImpact( %theirObject ) )
    {
        // Quit.
        return;
    }
    
    // Actor?
    if ( %theirObject.isMemberOfClass( "pskActor" ) )
    {
        // Damage the Target.
        %theirObject.takeDamage( %ourObject.ProjectileDamage, %ourObject, true, true );
    }

    if ( %OurObject.isMemberOfClass( "BurningPineConeProjectile" ) )
    {
    %effect = new t2dParticleEffect()
    {
      scenegraph = %this.getSceneGraph();
      Name = "Fire";
      effectFile = "~/data/particles/FireEffect.eff";
      useEffectCollisions = "1";
      effectMode = "KILL";
      lifeTime = "3000";
      canSaveDynamicFields = "1";
      Position = "41.000 -6.000";
      size = "8.000 8.000";
      CollisionMaxIterations = "1";
         mountID = "149";
    };

  %link = %effect.mount(%theirObject, "0 0");
  %effect.playEffect(true);
  %effect.isPlaying = true;
  %this.BurnActor();
    }


    //There's sometimes a little trouble with this part so we're fixing it...
    if ( %theirObject.isMemberOfClass( "SnakeClass" ) )
    {
        // Damage the Target.
        %theirObject.takeDamage( %ourObject.ProjectileDamage, %ourObject, true, true );
    }

}

function pskProjectile::BurnActor( %this, %ourObject, %theirObject )
{
if( isObject( Fire ) )
    {
       %theirObject.takeDamage( 25, %ourObject, true, true );
        %this.schedule(1000, 0, "BurnActor");
    }
}

The problem is that it (obviously) doesn't work.

The projectile fires but when it hits the target, the fire effect is not spawned and it doesn't burn them away. Any help is greatly appreciated!
