Here is the problem:

I have one worksheet (we'll call it "Segment Data") containing more rows
than are normally necessary, to accomodate projects that happen to have more
segments that are average. For most projects, many of the rows will not be
needed and will, consequently, be left blank.

A second worksheet (we'll call it "Sales Summary") will be designed with as
many rows as "Segment Data" and will be auto-populated with data from the
corresponding rows in "Segment Data." Therefore, if any rows in "Segment
Data" are unused and are left blank, the corresponding rows in "Sales
Summary" will be displaying all zeros.

Is it possible to use Conditional Formatting or other techniques to hide the
rows in "Sales Summary" if their corresponding rows in "Segment Data" are
blank?
