How do I add a reserve to an item?

[StealthPolarBear]

have already listed it and now I want to add a reserve. When I go in to modify it, I only get the option to add a BIN price - does anyone know where I should look?

OK i figured this out in case anyone needs to know
when you go to revise your item, you only get some of the options. At the top of the page there's a link to "show more options" or something like that, which takes you through to everything you could possibly need
