I am trying to simplify my code by adding a for loop that will load and compute a sequence of code 10 time. They way i run it now is that the same 8 lines of code are basically reproduced 10 times. I would like to replace the numeric value in the code (e.g. Bin1, Bin2....Bin10) each time the loop goes around. Below i tried doing this with a simple for loop and adding the string character before each numeric value. I need to first load the data then calculate, im sure this is possible as i have seen it done but cant seem to reproduce it in my own code. Hope my question is clear and i hope someone can offer some guidance.
