How can I fix rotation on my fence blueprint?

How can I get the railings to face the posts.

Here is how it currently looks:

Here is the blueprint so far. The Sequence just leads to the same stuff as you see in the screenshot except the mesh is swapped for a railing instead of a post.

Can anyone point me into the right direction?

You are getting the spline tangent/normal corresponding to the beginning of the bar static mesh. You should use a find look at rotation node to get the correct rotation between poles.
