(solved) Need help connecting nodes

I can't make these nodes connect. please help. (if I did this right there should be some screenshots below)

 

You are getting the letter l and the number 1 mixed up.

As an example, the node is called "bl15" (with a letter l followed by a one), but in the beams section you are using "b115" (with 2 ones).
And the same for the other nodes.
The nodes you wrote in that beams sections don't exist, so such beams can't get created and you get the "link target not found" error message.

 

wow... the difference between a 1 and an l is like one pixel. thanks 07
