I have zero Excel knowledge so I can't do it myself, but can you make it so that the "Total" score is calculated automatically out of the values we put in the different categories?
Yes it's pretty simple. If you're using Excel, once you got the values filled in the other cells of that row, you click on the empty "Total" cell and Press the Auto Sum button, and hit enter, which should automatically calculate the total for you, just like in this video:
Remember to always save in Ron's Editor after editing the scores, so just before calculating the totals in the app. Also remember to refresh in Ron's Editor after pressing the "Calculate Totals" in the above app, to see updated totals.
