.css style works in everything but Firefox! Deadline passed yesterday, any help VERY MUCH appreciated!

Hi there,

Glad to be signed up, I wonder if there is anyone out there who may be able to help me with this issue I am having? I am working as a junior developer for a software company, I am developing a page at

www.resonline.uk.com/standingstones.net

(called intro.aspx)

The page displays properly in all browsers I tested EXCEPT for Firefox, which will not display the 'Next' button allowing the client to go on and place their holiday. The NEXT button sits just above the calendars on the page.

I have 2 style sheets, the one we use as standard, and the one the client sent me. So I declared them both. There must be something untidy because FireFox is not allowing the button to be shown.

I'm 2 days behind schedule because of this one small problem and my boss is currently waiting in Scotland with the client until I finish the online reservation pages! Doh!!!!!!

Very much hope someone can spot what I have done wrong, thanks so much for your time reading this and would be extremely grateful if someone could reply,

Kind regards

Jim
