Base Map Transparency Slider Code Please

Question

I have three base maps: aerial, topo and streets.  I would like to create a slider to change the transparency for the three layers such as this map from the code gallery- http://maps.hamiltontn.gov/hcflex/

Can anyone point me in the direction of this code?

If I try it with just two layers I'm thinking I have to sent the alpha to the inverse of the slider for on of the two layers?  I have a slider working but only for one layer at a time.

Thanks in advance!

Mary,

I'm new to Flex api, just have a question as to how do you uses your code to work in Flexviewer2.2.
All I want to do is create a transparency slider to work for all 3 basemap layer.
Thanks,

Ha Tak
