Hi Alan,
Thank you for posting on our forum! I am using Lumerical 2024 R1.3, and I tried to run the .lsf script . I didn't encounter the behavior you are discribing, hence I would suggest to upgrade to the latest version. Also, I think that the sweeps are already run on our onine file and there are date there, so you can run the script even by keeping the line 7 with as a comment.
Hope that was helpful! Let me know if I can be of further assistance.
Kind Regards,
Niki
