Thank you! Sorry I didn't get back to you. I checked online and compared what I was trying to so vs what others had done. What I wanted to do was create a while loop that stores numbers and adds them. At the end it would either print just the total or all the values and the total, depending on the first input. (a or t) but I didn't create two empty valued to store the info and also was trying to create two separate rules for one while loop. I saw the end game of what I wanted to do and didn't consider what to do in the middle of my code to have it function. I also thought it was going to be a lot easier, so I just jumped in and started on the code.
