PLEASE  I DUNT KNOW HOW TO DO IT AT ALL

var x, y, button : int 
var paddleHEIGHT: int:=5 
var objectVX, objectVY, x2, y2 : int 
objectVY := 10 
objectVX := 10 
x2 := maxx div 2 
y2 := maxy div 2 
const ballRad : int := 5 
setscreen ("offscreenonly") 
loop 
delay (30) 
cls 
mousewhere (x, y, button) 

drawfillbox (x,13,x+60,paddleHEIGHT,black) 

drawfilloval (x2, y2, ballRad, ballRad, black) 
x2 += objectVX 
y2 += objectVY 
if x2 > maxx - 5 then 
objectVX := -objectVX 
elsif x2 < 5 then 
objectVX := -objectVX 
elsif y2 > maxy - 5 then 
objectVY := -objectVY 
elsif y2 < 5 then 
objectVY := -objectVY 
end if 
if x2 > x and x2 < x + 60 and y2 <  13 then 
   y2 := -y2 
end if 
View.Update 
end loop

You're off to a good start.  First off though, please use either [code] or [syntax] tags when posting code.

You have the basics of the ball movement down.  You have your x- and y- velocities, as well as your x- and y- coords.  Now, you simply need to use some if conditions to determine when the ball has touched the lower bounds of the screen (when x=0).  At this point, the player's lives would go down.
You'll also want to make sure that this condition makes sure that the ball has indeed touched the bottom screen and not just the paddle.  When it touches the paddle, it can simply bounce as it's doing right now.
When all lives have been used up, exit your main loop and display the closing message.

In other words you do know what you're doing.  Just apply your thoughts into the code.  Post up when you're done so we can look over the final product.
