I have a table with 4 columns. The first is a serial number, the second is time when a foot-pedal is activated. The third is a numerical value. There are X number of rows where X is a variable that grows by one every time a foot pedal is pressed. At the moment column 3 is unknown. I would like the user to input column 3 and the moment he does that I would like column 4 to be the time when column 3 is entered. This should be possible for all the rows. How do I do this? Any pointers? Thanks.
