Cannot rescale a constant/zero column error.

I am trying to run the R Script below, I have actually simplified it to just
this part that is causing issues.  When I run this script I continue to get
an error that says "cannot rescale a constant/zero column to a unit
variance".  I cannot figure out what is going on here.  I have stripped down
my data file so it is more manageable so I can try to figure this out.

The data.txt file that is being read looks like this:


I have made this file very basic on purpose to see if I could get this to
work, but it is not working.  Of course once I get this to actually work I
will expand the data file to match the data I am actually using.  



If I change the attribute in the prcomp function to scale=FALSE of course I
can run my script.  But if it is scaling...which is causing the issues, it
errors.

Any help would be GREATLY appreciated.
