Curve Driven Pattern Chain Link Help Please

I have found many shared "chain link" files that show how to get my chain to follow the spline I have drawn but I am having major issues.  For some reason mine barely follows even the most slight spline.  It seems so simple yet I am struggling to find out where my issue is.  What am I doing wrong?  Please advise.  I am a first time poster as well.  Thanks so much.
