Browser Layout issues

I'm sure this is a question asked many times in this Forum (I have done several searches, but can't find a satisfactory answer), so I'll ask again!

I've created a webpage in Dreamweaver 8 (using elements from Flash CS3). In Dreamweaver, everything looks fine, but when I open it in Firefox and IE everything gets skewed, bits of code appear on the site and whole elements are missing.

The link is

www.supersmashinggreat.com (you need Flash player 9, to view it 'properly')

The main problem is that the super, smashing and great are shifting about. Each word (in Dreamweaver) is in a seperate table, nested in a layer. Each of them should be horizontal, but for some reason when I upload the page 'smashing' becomes vertical.

I'm fairly new to dreamweaver and this is the most complicated page I have made, but I've not experienced these problems before.

Any help would be great,

Thanks
