Hello,
I get this error when trying to compile:
error 181: function argument named 'topmenu' differs from prototype

This is the code it's referring to:

PHP Code:

public void OnAdminMenuReady(TopMenu topmenu) {
    
    if(obj_dmcommands == INVALID_TOPMENUOBJECT) {
        OnAdminMenuCreated(topmenu);
    }
    
    if(topmenu == hAdminMenu) {
        return;
    }
    
    hAdminMenu = topmenu;
    
    // TODO: Add stuff to the menu
    
} 


It also gives me the same error on OnAdminMenuCreated()

What does that error actually mean?
I was following this tutorial.
