Problem with getElementById?
I have been creating a page with Javascript embedded and it works fine. I now want to transfer the script and link it to a js file. However when I do this the getElementById function is returning a null value. How do I get it to return an object from the actual web-page?
An example is
document.getElementById("BUYGS").addEventListener("click",buygoldsingle,false); (Firefox)
document.getElementById("BUYGS").attachEvent("onclick",buygoldsingle); (Internet Explorer)
I copied over the java and pasted it into a text file renamed with a js.
If it helps the page that works is www.portwood.co.uk/AOtravelinsurance.htm and the page that doesnt work is www.portwood.co.uk/AOtravelinsurancefull.htm - the script is stored at aojava.js
I added a small routine
function popup()
{
alert("Hello World");
alert("Hi There");
temp = document.getElementById("bronzesingle");
alert(temp.value);
}
This works in Firefox but fails in IE8

Mke sure the id of the element on the web-page is exactly the same as the string written into the parameters of the getElementById() function. Otherwise it will return null.
