Excel VBA code needed to copy row if criteria is met - arrays

Question

I have an excel document with two sheets. Sheet 1 has columns A-Q and Sheet 2 has columns A-H. What I need is a code that will copy the information in a row from sheet 1 to sheet 2 if the criteria is met. The criteria is the word "Awarded" in column L (Sheet 1).
Also is it possible to have only specific columns in the row copied?
A B C D E F G H I J K L M N
X X Awarded X X
I would like to have only columns C,D,M, and N copied from the row if the word "awarded" is in column L. This information would be copied to Sheet 2 in the following fashion
Sheet 1 Sheet 2
D --> B
C --> C
M --> D
N --> F
I hope I'm being clear. Thanks in advance and let me know if I need to clarify!+
This is the code I currently have, which works. Only problem is it copies the entire row of information into sheet 2 when I only want rows D,C,M, and N to be copied.
Sub testing()
Set a = Sheets("Sheet1")
Set b = Sheets("Sheet2")
Dim d
Dim j
d = 1
j = 2
Do Until IsEmpty(a.Range("L" & j))
If a.Range("L" & j) = "Awarded" Then
d = d + 1
b.Rows(d).Value = a.Rows(j).Value
End If
j = j + 1
Loop
End Sub

First what you should do is change your data structure. Assuming you are using Excel 2007 or later, there is a great feature called Tables. If you highlight all of your data and go to Insert->Table, select the "My Table Has Headers" checkbox, and press ok, you will see a nicely formatted table. Do that for both of the data sets on each sheet.
This is more than just pretty formatting though, it is what is called a ListObject. In your VBA code, use the following to reference it:
Dim Table1 as ListObject, Table 2 as ListObject
Dim HeaderIndex as Integer
Dim MyColumnRange as Range
Set Table1 = Sheet1.ListObjects("TableName1")
`Change the table name under Formulas->Name Manager
Set Table2 = Sheet1.ListObjects("TableName2")
HeaderIndex = Application.WorksheetFunction.Match("ColumnLHeaderName", _
Table1.HeaderRowRange, 0)
Set MyColumnRange = Table1.ListColumns(HeaderIndex).DataBodyRange
MyColumnRange.Select
At this point, the select statement is just to show you what range you are dealing with now. The HeaderIndex refers to the header sub component of the table ListObject. Using Match() will allow you to specify the name of the column header without hard coding it's position. (i.e. if your data starts in column A, the header value in column L will return HeaderIndex = 12)
Now that you know what column you want, you select the ListColumn object. Then, the DataBodyRange is used to select the range component of that object. This is the entire range in that column. You can then iterate down the list to find the data you want.
EDIT: Updated Example:
'Specify your ranges you will be copying from beforehand, adding as many as you need here.
HeaderIndex_D = Application.WorksheetFunction.Match("ColumnXHeaderName", _
Table1.HeaderRowRange, 0)
HeaderIndex_C = Application.WorksheetFunction.Match("ColumnXHeaderName", _
Table1.HeaderRowRange, 0)
HeaderIndex_M = Application.WorksheetFunction.Match("ColumnXHeaderName", _
Table1.HeaderRowRange, 0)
HeaderIndex_N = Application.WorksheetFunction.Match("ColumnXHeaderName", _
Table1.HeaderRowRange, 0)
Set ColumnRange_D= Table1.ListColumns(HeaderIndex_D).DataBodyRange
Set ColumnRange_C= Table1.ListColumns(HeaderIndex_C).DataBodyRange
Set ColumnRange_M= Table1.ListColumns(HeaderIndex_M).DataBodyRange
Set ColumnRange_N= Table1.ListColumns(HeaderIndex_N).DataBodyRange
'Now, loop through each row that exists in your table. If the testing
'condition contained in MyColumnRange you previously defined is met,
'then assign the destination cell (which can be defined in the same way
'as above) equal to the lookup range's current row value (specified by i)
For i = 1 to MyColumnRange.Rows.Count
If MyColumnRange(i) = "Awarded" Then
DestinationCell1.Value = ColumnRange_D(i)
DestinationCell2.Value = ColumnRange_C(i)
DestinationCell3.Value = ColumnRange_M(i)
DestinationCell4.Value = ColumnRange_N(i)
End If
Next i
