Drop down menu falls under flash

[rhs]

I know this issue has come up before, but I could not find anything when I did a search on Sitepoint. I have a dropdown menu with the submenus that want to fall under the flash movie in IE7. I have tried <param name="wmode" value="transparent" /> but this is not working. Any suggestions for controling this in the css? Here is my css if that would help. Thanks

#csstopmenu {
PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 2px 0px 0px; PADDING-TOP: 0px; LIST-STYLE-TYPE: none; position: relative; z-index:100; BACKGROUND-COLOR: #374b78
}
#csstopmenu UL {

We're going to need to see the HTML as well and preferably a link to the page.
