I have a list of names, many of which repeat in one data table. I would like to populate new columns with each subject's age, sex, and other demographic information. This information is stored in a separate data table. From previous forum responses, it seems like the Update Table function is recommended as the easiest way to mimic the VLOOKUP function in excel. Unfortunately, I can't seem to make the function work how I need it to. I set the two columns with patient names as the matching variable, and then select the columns with the demographic information I would like transferred. However, I get a notice that no data has been transferred and my sheet does not update. I'm not sure what I'm doing wrong!
