Ok here is what I want to do: I want to have an image with a rollover effect, but also when you roll over the image I want a dropdown menu to appear.

I put the image rollover code on the image itself and then put a hotspot over the image with the dropdown code in that.The codes work fine when used alone, but when I put the image map over the rollover image I can't get the image rollover to work, just the dropdown menu works.

Anybody have any ideas as to what I can do? Thanks, I appreciate it.
