date stamp for checked column
I am looking for a way to date stamp a check in a column. I have employees who conduct monthly inventories of tool kits and would like to show that they are doing them on time. I have this set up with a column for each month after the kit and individual tools are populated in rows. I would like them to be able to check each tool as they inventory (or scan a QR code with their phone attached to each tool to check the box) and have the column next to the month date time stamped. As of now the next row just turns green, but there is no way to prove that I didn't check all the boxes for the year yesterday. Thank you for any ideas.
