HELP with Flash and Timelines in Dreamweaver!

I am using a timeline and Flash sounds in Dreamweaver. I added a behavior
to the timeline which would play a sound, but my browser gives me this
error:
"Object does not support this property or method"
The browser says the error is on line 97 character 12. Which is the script
DW puts in to control Shockwave or Flash. I tried putting in a plain text
link that would control the Flash to test it. Still got the same error. I
also put a text link on a clean document to control the Flash. This worked
fine. So, I can only think that it has something to do with the fact that
there is a timeline present.

So, my question: Has anyone ever seen such an error? If so, how did
you fix it?

Thanks,
Matt
