Error when setting user dynamical scale

I guess you need a tutorial on fortran:
Here is a good one
https://web.stanford.edu/class/me200c/tutorial_77/

Look in particular at:
https://web.stanford.edu/class/me200c/tutorial_77/05_variables.html

I'm pretty sure you should get some IT guy which can help you on your university
to either have some lecture on fortran programming and/or to help you to debug such kind of issue.

Cheers,

Olivier
