Professional :: Making Button On Imported PSD

It seemed like a simple process but I cant seem to get this right... I got a button there, but the URL wont go, i.e., the click does nothing. I imported a PSD layered image to Flash CS3, into a new blank layer. I need basically an area of this PSD to be "image mapped" so what I did was create a rectangle with the rect tool, over the area I needed the hot spot. Here I tried to do a transparent box and border (alpha 0) but the outline is still there even though the box is "empty." (I did select the transparent box, no color, and tried alpha, both same result). I made that into a symbol, then I double clicked into there to fill in the key pts for the over, hit, etc., states.... I don't have any effects here btw, as simple as we can get.

After that I right clicked on the button and entered the action script ("reserve" is the name of my button symbol)
reserve.onRelease=function(){getURL("[URL]");}
Which gave no errors on validation. When I preview in Flash, everything looks good except the thin black border and the fact that when the button is pressed, nothing happens.
