trying to use llFrand for adjusting tajectory

why does'nt this seem to be producing a random
direction they all seem to be going south west never north east or any other direction ?
probably a quadrangle thing but anyone got the simple fix for this?

vector pos;

default
{
    state_entry()
    {
        // set the die point for the thing to go to before it dies so it doesnt ghost
      pos =(llGetLocalPos() +<0,0,400> ); 
               }
    on_rez(integer start_param)
    {
       llSetPos(llGetLocalPos() -<0,0,0.1> ); 
               llSleep(1);
      float randm;
                 float rand;      
               randm = -0.3+llFrand(0.15);
               llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> ); 
                randm = -0.3+llFrand(0.15);
                llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> );   
              randm = -0.3+llFrand(0.15);
              llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> ); 
               randm = -0.3+llFrand(0.15);
               llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> );  
              randm = -0.3+llFrand(0.15);
              llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> );       
              randm = -0.3+llFrand(0.15);
              llSleep(0.2);
               rand = -0.3+llFrand(0.15);
               llSleep(0.2);
                llSetPos(llGetLocalPos() +<randm,rand,0.5> ); 
                llSleep(6);
            llParticleSystem([]);
            llSleep(1);
            llSetAlpha(0,ALL_SIDES);
             do{llSetPos(pos);}while(llGetPos() != pos);
             llSleep(5);
              llSleep(1);
              llDie();
              llSleep(3);
               llDie();
         }
         
      }   

also if anyone could show me a smoother way to do the same thing that'd be cool
basicallt rezzing things that go up 3 or 4 meters and rez another thing then vanish.

I suspect your problem is this:

llFrand produces only positive values.

<+x,+y,+z> will only move in one direction. You need negatives too.

index =llRound(llFrand(5));
               posnegindex =2.5-index;
                divedbyten =posnegindex/5;
               randm=divedbyten;
                index =llRound(llFrand(5));
               posnegindex =2.5-index;
                divedbyten =posnegindex/5;
               rand=divedbyten;
                llSetPos(llGetLocalPos() +<randm,rand,0.5> ); 

ok thanks ya tinkerd a while longer and came up wity this seems to
do pos and neg numbers
