ActionScript 3.0 :: Add The Final Results In A Text Field?

i have a quiz and i want to add the final results in a text field. First i have an array which i push the score to. now i need to know how to put that array in to a text field. i have this code -

code:

for (var s:int = 0; s<arrscore.length; s++)
{
score_txt.text = (arrscore[s]);
}

but it just puts the latest score into the textfield. so if i get 3 it puts in 3 and if anyone does it again it puts their score in instead of mine. i want it to show all the different results in the texfield on an individual line
