why do i get bumped out of my code?

I've been working with image swapping, and while my code works correctly the first time, on the second run, it terminates abruptly before swapping the actual image (which I verified using alert messages). I call my code from an onClick via an image within the page itself. Could someone please take a look and tell me what I'm doing wrong? It's driving me nuts! :eek:

function showNewPic(p){
//load selected Array if not already loaded
if(currentpic == 0){
var images = new Array(pickArray.length-1);
for (var i=0; i<(pickArray.length); i++) {
images[i] = new Image();
images[i].src = "images/portfolio/" + pickArray[i] + ".gif";}
}

if(currentpic + p > pickArray.length-1){
currentpic = 0; }
else if(currentpic + p < 0){ currentpic = pickArray.length;}
else{currentpic = currentpic + p;}

document.pfolio.src = images[currentpic].src;
}
</script>

I figured it out:
It was because the image array was undefined the second time I tried to call it - a rookie mistake I suppose. I separated out the image loading from my function and created a new array name and now the code works. Hooray!
And thanks anyway :)

Hi Dave,
Actually, I had forgotten to turn on error message reporting after I had reinstalled my OS. *blush*
But now I've got it and hopefully I won't make this same mistake again. Thanks for the tip and I'll try to provide all the information next time.
Cheers! :)
