This looks like a recorded macro. It is not necessary to do
all that selecting. This does the same thing without leaving a
copy of the range  in the clipboard.

ActiveSheet.Range("A2:S13", Range("A2:S13").End(xlToRight)).Copy _

Loop through each cell in the range and test its value separately.

Dim rngCell As Range

With Worksheets("DMH")

For Each rngCell In .Range("d2:d15")

Next rngCell
