Center 'Post Type' Search Options

I am trying to center the search option buttons (i.e For Sale & Rental) to the middle of the form.

If I use ALIGN=”center” against the whole object then it centres all of my labels too – but I want them to remain left aligned – it is just the search option buttons at the top that I want to be centred.

I have tried a few options in the CSS file – but nothing seems to work.

Any suggestions ?

The search form can be found at http://www.ridgetek.co.uk/southestates/

Thanks

Pete
