Have a look at this topic, i've done one of these menus before, the code fully works without errors so might be a better platform to start from.http://w3schools.invisionzone.com/index.ph...wtopic=5098&hl=Let me know how you get on :)

cheers scott that help loads.i have a question, the "objectID", i changed the name of it in my code, and then it didnt work, so obviously "objectID" is an attribute name. right? also, is it an attribute of the id passed into the fucntion from the html page or something else.just wondering for future reference. thanks again :)

Without seeing the code I would guess it is the ID of an HTML element in your document.It is probably passed to a function or used to get the lement like this

document.getElementById(objectID);

Yes aspnetguy is correct.This is the function, note that if you change one objectID you must change them all or it won't work.function toggleMenu(objectID){ var object = document.getElementById(objectID); if (object.style.display =='block') object.style.display='none'; else object.style.display='block'; return;}And this is the function call.<a href="java script:toggleMenu('menu1')">BREAKFAST</a><a href="java script:toggleMenu('menu2')">LUNCH</a><a href="java script:toggleMenu('menu3')">DINNER</a>So objectID is the value of whatever link was clicked ie menu1, menu2 or menu 3Is that clear enough :)
