Adding New Sub Menu Pages

[Adebusola]

Double click on the Nav Bar to oven the Navigation Bar Properties menu.

Click the + next to the page you want to add a sub menu.

Double click the Double Click to Add New Menu, add a button title and link

Thanks for your help.
My problem is that when I now try to create a 'New Page" for the sub menu pages the new page is added to the list on the "Main Navigation Bar". For example, I have 8 main menu pages and the add page 9 that is for a sub menu page. What i end up i "page 8 a" added to the main menu links.
I have done another site before and did not have this problem but cannot remember how I did it.
How do I prevent this from happening.
Thanks
