FW: Scripts picks random elements from array , but it repeats sometimes

[FLAHERTY, JIM-CONT]

 
Hello , My script picks out random elements from an array , but it sometimes
repeats ( which is no good) .. I want to prevent this , Do I delete the
element from the array .... or is there a better way ? And how do I do
either ?  
 
 
 
my mistake here is the code 
 
 
 
 
while($numofques > 0) {
    $index   = rand @numbers;
    $element = $numbers[$index];
 
 
 

 
 
 
 
 
Thanks 
Jim
