Read this if your track doesn't work.

At first these rails didn't work and I figured that I had the same problem as other bad reviewers here. But I was able to fix the problem.
The center rail was the problem. I cleaned the "pins" and the rails with Goo Gone. And then I carefully squeezed the center rails so that there was more friction upon insertion. This gave better contact. If you squeeze it too much the rails won't go together. So just pry it apart until they fit.
Hope this works for you.
Good luck and have fun.
