Simple SWF File problems

Hello all, im trying to create a very simple swf file, but have come  across some problems.

The file i want to create is very much like this - http://davidtest.webcastglobal.com/swf2/flash.swf

This swf allows me to import it into Flex, and control which frame is  being viewed.

I achieve this using a app that can be found here -
http://davidtest.webcastglobal.com/swf2/Main.html

When you press Next or Previous, it jumps forward or backward a frame.

Now i want to create a swf file like the ball file, although it will  just contain a series of images, 5 for example.

I tried creating such a file in Flash, using both AS2 and AS3.

I created a project with 5 frames, and put an image on each frame,  i  then put the "stop();" tag on each frame.

When i imported it into my flex app, flex cudnt communicate with it.

So the ball flash file has been made in a different way ?


Can anyone shed some light on the situation please?
