Layers mouse over

[arjay171]

Hi
I've attached a file I'm having trouble with. It's made with WD6.
In the top left I have put the accommodation button. I've linked this to 'mouse over' to a pop up speach bubble on layer 'acc'. However, when i preview the site the speach bubble shows on the index page, not just when the mouse goes over the word accommodation. I've done these pop ups before and they normally work and I can't see what's going wrong.
