Change

You have the option of filling in either a Change cell, or directly updating the Total cell (in which case the appropriate Change cell value will be calculated).  

The number that you enter in the Change field will be added to any existing number that is already displayed in the Total field.  

You can enter a positive or negative number in this cell, however, the Total cell cannot contain a negative value.  

Supplying a value in this field (either directly or indirectly) indicates which cells you would like any changes to affect).  

You are required to make an entry in a change cell, even if the change does not include a change to the number of hours (e.g. suppose you are simply making a bill rate adjustment).  In these cases, you will still need to provide an entry in this cell as to indicate which cell the bill rate adjustment applies too.  In such cases, you can simply enter a zero in the change cell.
