    <p>Further to my comment above which includes a <a href="https://stackoverflow.com/questions/10714251/excel-macro-avoiding-using-select/10718179#10718179">link</a> which talks in detail on avoiding <code>.Select</code>.</p> <p>Here are my <code>three</code> cents.</p> <p><strong>A. Declare your objects/Variables</strong></p> <p>It becomes easier to work when you have declared your Variables/objects. This ensures that you do not have to type repetitive code. For example</p> <pre><code>Range(Cells(2, 2).Address, Cells(5, 5).Address).THIS Range(Cells(2, 2).Address, Cells(5, 5).Address).THAT Range(Cells(2, 2).Address, Cells(5, 5).Address).THIS etc... </code></pre> <p><strong>B. Ensure that you fully qualify your objects and work with them</strong></p> <p>This is the most common cause of errors. Consider this line.</p> <pre><code>Range(Cells(2, 2).Address, Cells(5, 5).Address) </code></pre> <p>Here Excel is assuming that you are working with the current sheet. What if you are not. See this example</p> <pre><code>Sheets(2).Range(Cells(2, 2).Address, Cells(5, 5).Address) </code></pre> <p>Here the <code>Cells()</code> object are not fully qualified and can cause an error. See this <a href="https://stackoverflow.com/questions/14388270/setting-a-chart-source-data-based-on-a-variable-cell-range-in-vba">post</a></p> <p><strong>C. Cut out the extra/repetitive code</strong></p> <p>The Excel constants <code>xlEdgeLeft</code>, <code>xlEdgeTop</code>, <code>xlEdgeBottom</code>, <code>xlEdgeRight</code> etc each is equal to a number and that too in increasing order. If you type it in Immediate window then you can check it's value</p> <pre><code>'~~&gt; This will give you 7 ?xlEdgeLeft </code></pre> <p>So we can actually take advantage of this and shorten out code.</p> <p>See the code below</p> <pre><code>Option Explicit Sub Sample() Dim ws As Worksheet Dim rng As Range Dim i As Long '~~&gt; Change this to the relevant worksheet Set ws = ThisWorkbook.Sheets("Sheet1") With ws Set rng = .Range(.Cells(2, 2).Address, .Cells(5, 5).Address) With rng .Borders(xlDiagonalDown).LineStyle = xlNone .Borders(xlDiagonalUp).LineStyle = xlNone For i = 7 To 10 'xlEdgeLeft = 7 : xlEdgeTop = 8 : xlEdgeBottom = 9 'xlEdgeRight = 10 With .Borders(i) .LineStyle = xlDouble: .Color = -16777216: .Weight = xlThick End With Next For i = 11 To 12 'xlInsideVertical = 11 : xlInsideHorizontal = 12 With .Borders(i) .LineStyle = xlContinuous: _ .ColorIndex = xlAutomatic: .Weight = xlThick End With Next End With End With End Sub </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
