[gradsusr] mysterious scripting error

[Love, Mr. Gary, Contractor, Code 7542]

Hi Jeff,



Your script must be local to you. I could not find it at 
ftp://cola.gmu.edu/grads/scripts/



Anyway I made a simple test script shown below that works fine, so there must 
be an assignment problem in you script probably with CpT.1 or CpT.nt.



function main()

nt=10

CpT.1=302984

CpT.nt=316526

a=CpT.1

b=CpT.nt

say a

say b

deltatheta=b-a

say deltatheta

return

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?
