Need help looping macro - excel

Question

I don't believe this is very difficult but I can't figure it out...
In column B, I have either "Original" or "Add" listed. Starting from B79 and moving upwards, the first time "Original" is displayed I want to draw a border from B#:N# on the bottom.
I don't know how to run proper loops within VBA so below is what I have so far which is missing quite a bit.
Sub Test()
Range("B79").Select
If Range("B79") = "Original" Then
Selection.End(xlToRight).Select
Selection.Borders(xlDiagonalDown).LineStyle = xlNone
Selection.Borders(xlDiagonalUp).LineStyle = xlNone
Selection.Borders(xlEdgeLeft).LineStyle = xlNone
With Selection.Borders(xlEdgeTop)
.LineStyle = xlDot
.ColorIndex = xlAutomatic
.TintAndShade = 0
.Weight = xlThin
End With
Selection.Borders(xlEdgeBottom).LineStyle = xlNone
Selection.Borders(xlEdgeRight).LineStyle = xlNone
Selection.Borders(xlInsideVertical).LineStyle = xlNone
Selection.Borders(xlInsideHorizontal).LineStyle = xlNone
Else: ActiveCell.Offset(-1, 0).Select
End If
End Sub
Here is my current attempt. I am just trying to get it to highlight the cells.
Sub Test()
Let x = 79
Do While x > 7
If ("B" & x) = "Original" > 0 Then
Selection.End(xlToRight).Select
Else: x = x - 1
End If
Loop
End Sub

Use a for next loop and don't select, this should do what you need. Make sure you read this code and understand how it relates back to your original code.
Sub Test()
Dim X As Long
For X = 79 To 1 Step -1 'Step -1 makes it go backwards
If Range("B" & X).Text = "Original" Then 'Notice I am not actually selecting anything in this code, I don't need to in order to manipulate it
With Range("B" & X).End(xlToRight)
For Each Border In .Borders 'Loop the borders so you don't have to name each one
Border.LineStyle = xlNone
Next
With .Borders(xlEdgeTop)
.LineStyle = xlDot
.ColorIndex = xlAutomatic
.TintAndShade = 0
.Weight = xlThin
End With
End With
End If
Next
End Sub
