Row 17 requests style code 16, which does not exist in the style file

[Rosanne]

When I try to run my excel file in Direct RT, the program tells me that Row 2 requests style code 0, which does not exist in the style file (.drt) for this session. But it does not request 0, but 1. Do you know what the problem is?

Rosanne--I think it's because you are missing the necessary WGR column which should follow the BGR column.

I have the same problem as Rosanne. I read the admin's comment on the row before having a problem, but it is hard for me to detect what could be that problem. Are there specific signs to look for systematically?
Thank you so much.

Can you attach or send your input file? Would be happy to take a look.
