The formula was working fine, I added the formula to pull if ATP-CTP find IN in the position column to change Instructor / Student to Instructor put isn't updating.
See the formula below:
=IF(FIND("/I", [INSAV_DSPLY_CMNT_1_TXT]@row) > 0, "Instructor", IF(FIND("/S", [INSAV_DSPLY_CMNT_1_TXT]@row) > 0, "Student", IF(Client@row = "Delta", IF(FIND("IN", Position@row) > 0, "Instructor", IF(Client@row = "ATP-CTP", IF(FIND("IN", Position@row) > 0, "Instructor", IF(Client@row = "Delta", IF(FIND("OQ", [Inst_Role]@row) > 0, "Student", ""))))))))
