[gradsusr] mysterious scripting error

[Jeff Duda]

I have this snippet of code:

a = CpT.1
b = CpT.nt
say a
say b
*deltatheta = b-a*
say deltatheta

where CpT.1 and CpT.nt have been previously defined.  When I run the
script, I get this output

302984
316526
Non-numeric args to numeric operation
  Error occurred on line 62
  In file mixing_diagram.gs

Line 62 is underlined and in bold in the code above. Why is this error
occurring?
