Mouse Overs on Image Map using Frames - Urgent

[katmac]

Hello

I have an image map with some tooltip code added - wich is fine.
Here is the link: http://mandatorymarketinginc.com/test/directory.htm
This code works cross-browser and is in frames.

Here is the problem, I now need to have code that when the user mouses overs a store name in the right frame (dir-right.htm) the location of that store (for example, location N) is covered with a png file I created. I have created images for each location on the map.

Right now the code I have for each png location file is hard-coded and is not working cross-browser at all.

Does someone know how I can write this code in JavaScript to allow me to do this?

Thanks so much.

I think probably your positions are off only because of margins or some such.

I think you only need to play with your CSS to make sure it is consistent across browsers.

Have you considered just dumping the (considered very obsolete) <frame>s and moving to more modern <div>s?
