Move two menu items to the right

Hi.

I have been tearing my hear out with this one & wondered if anyone may be able to lend some advice. .

on the top menu on https://www.copymusic.co.uk I would like to move profile & submit buttons (and another button not added yet) to the right hand side of the page, these will be replaced with small images at some point so will sit neat and tidy in the corner.

I can move the whole lot to the other side playing around with the CSS, but I want to keep the logo, login and sign up buttons on the left.

I have come across a few websites which suggest using

.custom #menu-item-*****{ float:right; } But I have tried this and it doesn’t work (I suspect this relates to a specific theme), I have also tried using li.#menu-item-*****{ float:right; } as you will probably see is still in my custom CSS File.

(**** = menu item number)

I can follow the most basic of instructions, does any one have any suggestions?

Thanks for your time.
