I'm trying to make a worksheet that counts time. I've done the period time to
the left and the days on top. I want Excel to count 20minutes every time
someone fills in a text in the cells below the days. If he/she for example
fills in math it should count 20 minutes in another cell where the total time
will be found. If nothing is filled in the cell it shall remain empty.
Counting the time is no problem the problem beginns when I want excel to
react when someone writes in a cell. I've got excel 97.
