Cannot see flash button on website!!

Hi,

I'm having bit of trouble with flash 8 button displaying on my website.
I created a button (that fades in color when mouse over).

I have tested that the flash button works fine(clicking the .swf file).

My problem is that when it is placed in my website i DO NOT SEE it at all... its just a empty table (which holds the button).

It does however indicate that the button is there as the small hand pointing symbol appears when hovering over where it should be.

I have tried it in both Mozzilla and explorer7 and cant see button in either!
When viewing in explorer though it says click/space to activate (under where the button should be). Clicking or hitting space bar doesnt do anything except remove the above message.

In addition to this, i have the button saved as html, which also works fine????? It just doesnt work on my phpmysql website.

Please help me
Thanks for listening

Tom :)
