Simple cycling banner script???…

I modified a simple cycling banner script from a reference book:

[QUOTE]

ad01 = “images/banners/428×60/ad01.gif”
ad02 = “images/banners/428×60/ad02.gif”
ad03 = “images/banners/428×60/ad03.gif”

function rotateAds(){

adImages = new Array(ad01,ad02,ad03)
thisAd = 0
imgCt = adImages.length

if (document.images){
thisAd++

if(thisAd == imgCt){
thisAd = 0
}
document.adBanner.src = adImages[thisAd]
setTimeout(“rotateAds()”, 3*1000)
}

}

[/QUOTE]

But it doesn’t work properly. It only will only cycle to the2nd image in the array and then is stops. I looked it over and I just dont see what I am missing. I my counter off?

Also in #JavaScript _↴
