Can this piece of code be adapted easily to delete a row when the active
cell value is less than 0?

Range("h6:h700").Select
Dim rngToSearch As Range
Dim wks As Worksheet
Dim rngFound As Range

Set wks = ActiveSheet
Set rngToSearch = wks.Columns(3)

Set rngFound = rngToSearch.Find("-")
If rngFound Is Nothing Then
MsgBox "No Deletions Found"
Else
Do
rngFound.EntireRow.Delete

Set rngFound = rngToSearch.FindNext
Loop Until rngFound Is Nothing
End If
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
End Sub
