Dijkstra's Algoritm Problem

I want to make it possible that I can see the path from one user to another and via whom the route went:

I want to pass the startnode and the endnode and then retreive the route between them.
In case I go from 5 to 15 (see table below), I want to have the following returned:
5-6-15
5-7-15

In case I go from 5 to 18 I want to have returned:

5-6-15-9-18
5-7-15-9-18

always up to a maximum distance of 6 steps.

I have the following table definition
tblFriends
OwnerCode  int
FriendCode int

this table contains content like:




5
6

5
11

5
7

6
5

6
12

6
15

6
11

7
15

7
5

9
15

9
18

11
5

11
6

12
6

13
6

15
6

15
7

15
9

18
9


As you can see, I store each relationship twice.


I have created the following SP to retreive the info, but dont know how I can get from these results to the results I desire as described above....
