Hi Mala, I don't remember exactly why but many of Max's scripts begin with an underscore "_" character at the start.

If you look closely at the files that you are copying you'll probably see they are actually named _DelCorners.htm and _DelCorners.js - note leading underscore _ character.

So when those files are copied into MOI's commands folder there will be a new command named _DelCorners available to use. The name you are using is missing the underscore _ character. That's why you're getting the error.
