Particles Help Please

High peeps,
Why won't this script allow me to move the object and have the particle follow? Also is there a way to keep it emitting 1 particle for as long as I like?

string pooftexture1 = "TEXTURE KEY";
float min = 1.0;
float max = 1.0;

Label()
{

    llParticleSystem([ 
        PSYS_PART_FLAGS , 0,
        PSYS_PART_FOLLOW_SRC_MASK |
        PSYS_PART_EMISSIVE_MASK | 
        
        PSYS_SRC_PATTERN,           PSYS_SRC_PATTERN_DROP,
        PSYS_SRC_TEXTURE,           pooftexture1,
        PSYS_PART_MAX_AGE,          1.0,
        PSYS_SRC_MAX_AGE,           0.0,
        PSYS_SRC_BURST_RATE,        1.0,
        PSYS_SRC_BURST_PART_COUNT,  1,
        PSYS_SRC_ACCEL,             <0.0,0.0,0.0>,
        PSYS_SRC_BURST_SPEED_MIN,    min,
        PSYS_SRC_BURST_SPEED_MAX,    max,
        PSYS_SRC_OMEGA,             <0.0,0.0,0.0>
    ]);
}

default
{
    state_entry() 
    {
        Label();
        llSetTimerEvent(30.0);  
    }
    
    timer()
    {
        llParticleSystem([]);
        Label();    
    }
    
    changed(integer change)
    {
        if (change & CHANGED_INVENTORY)
        {
            llResetScript();
        }
    }
}

At one point the particle did follow the object when moved but now it doesn't seem to work...

All help is very much appreciated!

Try this syntax :

        PSYS_PART_FLAGS , (0|
        PSYS_PART_FOLLOW_SRC_MASK |
        PSYS_PART_EMISSIVE_MASK),

The maximum PSYS_PART_MAX_AGE is 30 seconds.

Thanks for the help bro! Got it sorted
