Adding new buttons; changing position of old ones

[ahi]

Hi,
I'm a newcomer and dont have much experience on fireworks.
I have managed to design a menu, with rollover images (was relatively easy; i know nothing about slices and that kinda stuff, just play with the visual tools),
now i need to add a few more options to the menu, and it just doesnt work anymore.
i mean the whole thing breaks when i put it into a dreamweaver html file. i need these new menus incorporated into the old one. can someone plz help me!

thanks......
