formula to just show numbers?

Hey all,

Just a quick one, if c3 displays two digits and then a name how can I make cell a3 automatically display just the digits without have to type it everytime, I'm think I should be able to format with a formula cell a3 to just display the numbers but i'm a bit stuck..

eg

cell a3 cell c3
55 55 bob brown

Thanks!

grand, thanks alot!
