i'm trying to make a 3d linear gradient between two points, but i'm having trouble with my math... can anyone help?

ok, to make it clear in math terms , i have two points in space (gdata.start and gdata.end), i want to work out the distance of my point "p" from the plane who's normal is defined by gdata.end-gdata.start, with the point gdata.start being on the plane.

what am i doing wrong? (oh and i want the result in terms of the length of the distance between my start and end points).

gdata.start=Vector(0,-100,24);
gdata.end=Vector(0,100,0);
Vector norm=(gdata.end-gdata.start);
r=(p-gdata.start)*!norm/Len(norm);

heeeelp!
