Function not working on Vista

Question

I have this JavaScript function which is working in all the machines I tried except the one that is running on Vista. I am calling this function onload. what do you think is wrong with this one.

function isePad() {
    var epad;
    epad = window.document.esCapture1.ConnectedDevice;

    if (!epad) {
        alert('Sorry epad either is not Connected or/and drivers are not installed');
    }
}

What does “not working” mean? Does it throw an error or is the result not as expected? — Gumbo, Jan 20 '10 at 17:55
What is ePad? A device? A product? A platform? Can you give a link? — Pekka, Jan 20 '10 at 17:58

Well, maybe the ePad is either not connected or/and the drivers are not installed? :) Have you made sure they are? Do your user rights give you access to the device? Can you try running the script as Administrator? From what I hear, Vista is really a PITA rights-wise sometimes. How, when and where do you load this ePad thing? `window.document.esCapture1` is hardly available in WSH by default, it it? Is your question anserwed by jball's answer below (is it a syntax question) or is your device not working? — Pekka, Jan 20 '10 at 18:08

esCapture1 probably does not exist - You should check for it first:

function isePad() { 
    var epad; 
    if(window.document.esCapture1){
        epad = window.document.esCapture1.ConnectedDevice; 
    }

    if (!epad) { 
        alert('Sorry epad either is not Connected or/and drivers are not installed'); 
    } 
}
