winabe23, you joined this month—probably because you were having trouble with CSS and HTML and you have certainly come to the right place.
And here is a video tutorial by "zorro30mum." It's in two parts, but there is a link to Part 2 below Part 1.
The reason why I am posting all of these links in my answer is because you're using Spry. And Spry has been found wanting by Adobe and they are deprecating and abandoning it.
But in the meantime, the tutorials above will get you into understanding how this whole menuing stuff is done in CSS and give you the understanding necessary to do simple stuff, like changing the color of a background for a drop-down.
I hope this helps you make great websites!
