I tried posting this question earlier and received an error message, so I
apologize if this question shows up twice.

I'm trying to insert a bottom border on a range of cells, but I can't figure
out the syntax for the range. Here's what I currently have:

Range("B" & lastrow).Select
With Selection.Borders(xlEdgeBottom)
.LineStyle = xlContinuous
.Weight = xlMedium
.ColorIndex = xlAutomatic
End With

This works for column B, but I want the border to also be on column C and D.
I could add the same code for each column separately, but I'm wondering if
there is a way to do the entire range (B:D) at one time.

Thanks!
