Hi all , I wrote code that works just fine, however, I realized there were parts of the data I was using that had 0's in it for holiday.

Bottom line, this is code that calculated the weighted average of prices for 12 months (12 rows across) and Drows across. I'm trying to use the "do while is empty" approach but can't get the syntax to work. Here's the code 

For r = 1 To drows
 

    Totwavg = 0
    Tothours = 0
    priceavg = 0
            
         For n = 1 To ncontracts
             Do While IsEmpty(rngs.Cells(r, n + 1))
                  If r > drows Then Exit Do
                    Hours = Application.VLookup(PWR.Cells(1, n + 1).Value, vHours, 1 + OnOff1, False)
                    priceavg = PWR.Cells(1 + r, n + 1).Value * Hours
                
                     Totwavg = Totwavg + priceavg
                
                     Hoursbucket = 0
                     Hoursbucket = Application.VLookup(PWR.Cells(1, 1 + n).Value, vHours, 1 + OnOff1, False)
                     Tothours = Tothours + Hoursbucket
                 
                   Next n
                Worksheets("INFO").Cells(1 + r, 2).Value = Totwavg / Tothours
            End If
        Loop
Next r
