Error messasge...can not get study to run! (case 15065)

[jmd2407]

Hello,

I keep the error message " Row 3 requests style code 15, which does not exist in the style file (.drt), for this session."
I have never used DirectRT before, so I am very new to this. Can someone help me decipher this?
I have attached the file in question. I have also tried other files that say the same sort of thing. This study has been done successfully before, however, this is a new Lab we are trying to set up. So I am not sure of the issue.

Thanks,
Jessica
