Fence Diagrams

I am attempting to create a Fence Diagram in gINT following directions by Kathleen Holcomb from 2014.  These directions may be dated  for the version of gINT I am running (gINTCL).

After drafting the borings, I go through the steps as listed by Ms. Holcomb.  I select two borings from the "Boring Designation" line and click the "preview" icon at the top.  I then receive a pop-up window that is titled "Unable to output.".  Below this, it reads "Specified Points returned no data.  The following Points had no depth-related data: my boring #'s.  (After Pass 1)"

I unable to understand what this error message means or how to correct it.  If someone could direct me, I would be greatly appreciated.
