Thank you so much for the advice. The bysort actually worked once I inputted all of the variables at once in the sum portion of the command. I am meaning to show the average scores for each subject for now since not all of the subjects have multiple equal amount of time points. So this worked well so far. However, another issue that arose now is that all of the variables I renamed via the label var old var new var are now not displaying on the tables after bysort. Not sure why this occurred and would this lead to me being deducted points if the labels are not displayed on the tables in the log file?
Thanks!
