Attributes from 1 to 180 but not coming out in the right order.

[dandandanpie]

I have a couple of attributes which need to show numbers in ascending order from 1 to 180 but im getting an order I dont want and dont know how to fix.

I get this:

1,10,11,12,13,14,15,16,17,18,19,2,20,21... etc

but I want:

1,2,3,4,5,6,7,8,9,10,11

I cant see any way of doing this apart from using leading zeros like

001,002,003...010,011,012...130,131,132... etc which I dont really want to do if i can help it.

Anyone see what I can do to fix this?
