Image w/ description tooltip (Runtime Error + not working in IE)

[~jc]

1) Script Title: Image w/ description tooltip

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...agetooltip.htm

3) Describe problem: I just installed the script and it worked fine when viewed in Firefox (mouseover the link "view poster"), however it didn't seem to work in IE, and gave me a Runtime Error message:

A Runtime Error has occured
Do you wish to debug?
Line:118
Error: Invalid property value

Here's my webpage: http://www.skitheworld.com/about_war...ography00.html

I placed the following <div> just before </body> on the html:

<div id="tipDiv" style="position:absolute; visibility:hidden; z-index:100"></div>

The Javascript is linked to an external file mouseoverimage.js:

It looks like another script on your page causing an error in IE. Just to confirm this, try removing the other scripts on your page.

BTW, please note that your page is currently in violation of our usage terms, since the credit notice doesn't appear inline on the page. Please reinstate the credit notice:

I thought the credit notice was to be placed on the .js file.... I added it back to the html page now... Apologies.

I tried removing the other scripts and still got the same error message. Since I have those same scripts throughout the site I don't think that is the problem. Anything else I could try?

Thanks,
Judy

It looks like a simple typo:

///////////////////////  CUSTOMIZE HERE   ////////////////////
// settings for tooltip 
// Do you want tip to move when mouse moves over link?
var tipFollowMouse= true;	
// Be sure to set tipWidth wide enough for widest image
var tipWidth= 400;
var offX= 50;	// how far from mouse to show tip
var offY= 12; 
var tipFontFamily= "Verdana, arial, helvetica, sans-serif";
var tipFontSize= "8pt";
// set default text color and background color for tooltip here
// individual tooltips can have their own (set in messages arrays)
// but don't have to
var tipFontColor= "#000000";
var tipBgColor= "#ffffff"; 
var tipBorderColor= "##000000";
var tipBorderWidth= 1;
var tipBorderStyle= "solid";
var tipPadding= 4;

There could also be other problems.
