How can I fix this error?

Hi,

I am working on a piece of code and I get an error which i dont know how to fix. The piece of code below is AS2, I am trying to get it in a AS3 class. The problem is that the “dp” and the “v” variable give a duplicate error. So I tried to remove the word ‘var’ in front of it. Then ofcourse I get an error that the variable has not been declared yet. So I make a global variables at the beginning of the class. This removes the error, but the script does not work… Does anybody know how to fix this?


     function findIntersection(v1, v2)
        {
            var v3 = {};
            v3.vx = v1.p1.x - v2.p0.x;
            v3.vy = v1.p1.y - v2.p0.y;
            var dp = v3.vx * v2.dx + v3.vy * v2.dy;
            if (dp < 0)
            {
                //hits starting point
                v = v3;
            }
            else
            {
                var v4 = {};
                v4.vx = v1.p1.x - v2.p1.x;
                v4.vy = v1.p1.y - v2.p1.y;
                var dp = v4.vx*v2.dx+v4.vy*v2.dy;

                if (dp > 0)
                {
                    var v = v4;
                }
                else
                {
                    var v = projectVector(v3, v2.lx, v2.ly);
                }
            }
            return v;
        }
