Drop menus

[Ree_Ree]

Hi all, I’ve come accross a problem and can’t work out a solution. I’m trying to create a horizontal menu with 5 buttons and 3 of these buttons have drop down sub menus. I’ve followed the tutorial on this site and the drop downs are working fine except that one button makes all of them drop down at once. Is there anything I can do to prevent this? Any help would be great. Thanks in advance.
