[gradsusr] Problems with qdims.gsf ancillary script

[Mireieta]

Hi grads users,

I am trying to use the "tave.gs" script from Bin Guan's Grads Script
Library and I got this error:

'Error in math_int:  Argument not a valid numeric
  Error occurred on line 87
  In file tave.gs'

Looking at the script, I think the problem lies in the qdims.gsf ancillary
script... that is not working properly...

Has anybody found once the same problem and know how to resolve it?

Thanks,
Mireia
