Help in Importing Spline Curve Points into Different Coordinate System

Hi all,

I have an excel file with points I'd like to import into the part I have now. I made a coordinate system I'd like to put the spline curve on as well as a reference plane but I can't quite figure out how to do it. Everytime I try to import the points, the spline curve is automatically placed into the origin even when I preselect a different coordinate system and/or plane. Any tips would be appreciated. (By the way, the points are only on one plane, I kept the z-coordinate to all be zero)
