Sequence in groupfile, not in listfile


I was wondering what would cause a sequence to be found in my groupfile and not listfile when I run the make.shared command?

I get this error:
[ERROR]: 14045C::G77DK1X01A001F is in your groupfile and not your listfile. Please correct.


The most common cause of this type of error is forgetting to include the names file on one of the previous commands.
