Here is the input:
Activity, start week, end week
Based on the above info in the the first three columns of a spreadsheet, put a number or a string in the same row under the appropriate week number. So if an activity happens from week 18 (this week) to week 25, the corresponding columns would be filled with the number 1. So far I have not been able to figure out how to do this using macros. Seems pretty simple but I'm struggling since I have zero experience with Visual Basic
