I want the horizontal buttons to work like is working in :
http://web.sysrq.no/appolyon/21pzr/t...JS/header.html
when rollover "Panzer" button to have the JS Menu...

I tried over 2h..but i keep having errors:
1) because of the Preloading images ..i don't know how to get rid of
which throws me errors which i can't identify
2) Not even without preload function, rollover is working ... see http://web.sysrq.no/appolyon/21pzr/index.php for this problem
3) JS menus, i couldn't see the code working... i'm still stucked on rollovers with preload

All JS are generated by Macromedia Dreamweaver....i'm aware that is not best way to embeed JS but i don't have any other good option...i searched on the net more than 1h to find something ...any suggestions for JS which are proper for my needs and easy to be implemented into nuke are more than welcome
