Hi
I've got a simple rollover (well, supposed to be simple) but I can't get the thing to work - 'Error, Object Required' is the error message I get; I've tried everything, even copying and pasting code that is working with the same script but it's just not having it!
Please help
here's the relevant code:
<script src="includes/java_function.js" language="javascript" type="text/javascript"></script>
<script language="JavaScript" type="text/javascript">
function imgOver() {
}
function imgOut() {
}
</script>
then below in the body this is the html for example:
<a href="mailto:info@mysite.co.uk?subject=website%20enquiry" onmouseover="imgover('email')" onmouseout="imgout('email')">
<img src="image_bin/email_up.gif" alt="" name="email" width="161" height="11" border="0">
below is the script in the java_function.js file:
home_up = new Image
email_up = new Image
about_up = new Image
vehicles_up = new Image
terms_up = new Image
home_over = new Image
email_over = new Image
about_over = new Image
vehicles_over = new Image
terms_over = new Image
home_up.src = "image_bin/home_up.gif"
email_up.src = "image_bin/email_up.gif"
about_up.src = "image_bin/about_up.gif"
vehicles_up.src = "image_bin/vehicles_up.gif"
terms_up.src = "image_bin/terms_up.gif"
home_over.src = "image_bin/home_over.gif"
email_over.src = "image_bin/email_over.gif"
about_over.src = "image_bin/about_over.gif"
vehicles_over = "image_bin/vehicles_over.gif"
terms_over.src = "image_bin/terms_over.gif"
function imgOver(thisImg) {
document[thisImg].src = "image_bin/" + thisImg + "_over.gif"
}
function imgOut(thisImg) {
document[thisImg].src = "image_bin/" + thisImg + "_up.gif"
}
It's probably something very simple that's staring at me in the face!
thanks alot
Adam

Your functions are called imgOver and imgOut but you call imgover etc. Object required in JavaScript nearly always means you've got the case wrong on a function name.

Reminds me of when I first started playing with JavaScript, I spent hours staring at code that errored with "object reqired" because I had used "If" instead of "if"
