Help Please

I am a "Sortof Newbe SVG Scripter" i managed to cobble together a script.

It is not pretty but it nearly does what I want it to do !!

It can be seen at

When I click on the "Ear Button" - sound starts and the "Stop sound button"
appears.


On 'mouse over', it stops the sound.


BUT

I want the "Stop sound button" made invisible.


I have played for hours and cannot do it - please show me how !!

Thanks
Pete (Northolt UK)

Sorry - should have said that it only seems to work in Inernet Explorer with Adobe AddOn installed
