Multiple Flash Objects On Page, Delay Load By X-seconds?

the situation: I'm building a web page, and the client wants to have three flash galleries on staggered timing (i.e., the first one loads and runs, 4 seconds later the second loads and runs, 4 seconds later, third one loads and runs).

I've been trying to figure out how to use Javascript to handle the initial delay between each object, and the best I can figure is to use an onLoad to start the first flash (Flash1), and then call out a function with setTimeout to start Flash2 4 seconds after Flash1 loads, and the same thing for Flash3. However, my attempts thus far have failed, and all three load up at the same time.
