Wolfram Mathematica 6.0 B-splines

Hello!

I really need help about this one
On my college I got assigment to solve a problem in Mathematica 6.0
The problem is called B-splines degree 3
I need to create B-spline curve with 10 control points. Control points must
be mouse interactive so when you drag one of them the B-spline curve needs
to move...

I beg for a help cause there is no way i could make that i downloaded sample
from mathematica website
http://demonstrations.wolfram.com/BSplineCurveWithKnots/

but i dont know how to re-edit that project cause i dont know math code....
all i need to do with that exaple is to put more control points (10) and
make it degree 3 and delete all other interactive stuff on that exaple like
view interactive buttons etc....

Please help....
