Time Stamp

I would like to Time stamp Cell C1 and User stamp C2 whenever C3 is changed I would like to do this for columns C3 Thru ND3 these are daily operator logs. Can some help? Thanks.

Basically I am suggesting you intercept the onChange event and make the changes to the cells based on that event firing.
