I hope someone out there could help me fix this error. I am using a script from CHARMM-GUI for NAMD and when I am executing It kept saying [FATAL ERROR: can't read "boxtype": no such variable while executing]

There maybe something wrong with my method or I may be lacking some application to make this work but I really have no idea I hope you can help me. Thank you very much!
