You are trying to track the horizon centroid from a grid scalar. The respective parameter is not set, and AHFinderDirect thinks that grid scalar name is "" (the empty string). This is not a valid variable name.
You need to set the parameters track_origin_source_x[1], track_origin_source_y[1], and track_origin_source_z[1] to name three grid scalars that contain the location of the puncture.

Hi,
I'm trying to add by hand AHFinderDirect to the nsnstohmns.par i this way:

I get this error when running:

Can you please help me understand what I am doing wrong?
