Hi
Thanks, cast function worked..partially. Now its order 1,2,3,11, but decimal numbers are making problems. Right now i have problem with its making this: 0 0 0.8 0.9 0 0 0 0 1 2 ...
The second part, isn't this  a general problem? Or only I have sumgrades set to varchar? It comes from original install, i think. Or nobody sort attempts by grades?
