Sorting, Adding cost values for each input, Deleting row & writing a total

[JeremyA1976]

I have 7 columns that contain data. In column A, there can be identical descriptions for each input. In column K, there is a total cost for that row entry. In column N, I have quantities (if applicable) for each entry. I have the sort vba code figured out as such...

Sub UnMerge4Sort()



'UNMERGES CELLS, SORTS BY COLUMN A & FORMAT PAINTS ROW 9 DOWN
Application.ScreenUpdating = False


Range("A10:P58").Select
ActiveWindow.SmallScroll Down:=-48

Selection.UnMerge
ActiveWorkbook.Worksheets("CHARGE OUT FORM").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("CHARGE OUT FORM").Sort.SortFields.Add Key:=Range( _
"A10:A58"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:= _
xlSortNormal
With ActiveWorkbook.Worksheets("CHARGE OUT FORM").Sort
.SetRange Range("A10:P58")
.Header = xlGuess
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
Range("A9:P9").Select
Selection.Copy
Range("A10:P58").Select
Selection.PasteSpecial Paste:=xlPasteFormats, Operation:=xlNone, _
SkipBlanks:=False, Transpose:=False
Application.CutCopyMode = False

Application.ScreenUpdating = True

End Sub


I have merged cells, so it simply unmerges, sorts based on column A in ascending order, then formats the unmerged cells back to normal based on row 9 format. What I am having trouble with is figuring out how to combine identical rows and sum their square footage (column G), pounds (column I), cost (Column K) & quantity (column N). The code would have to:
1.) figure out which rows are identical based on column A.
2.) Sum columns G,I,K & N.
3.) Place it in memory or in a hidden cell to recall and write.
4.) Delete the original identical rows information.
5.) Write in one row that would include the new total sums.
6.) Then search for the next identical

EXAMPLE:

column A Material Description	column G Sq./Ft. or Lin.Ft.	column I LBS.	column K Cost	column M ACT	column N QTY
1" INSULATION 1 1/2 LB	150		64.5	12-60	-
1" INSULATION 1 1/2 LB	550		236.5	12-60	-
2 1/2" STICK PINS			32.5	12-60	250
2 1/2" STICK PINS			13	12-60	100
2x2x3/16" ANGLE	30	73.2	38.06	12-40	-
2x2x3/16" ANGLE	150	366	190.32	12-40	-

<colgroup><col span="11"><col><col><col></colgroup><tbody>
</tbody>

Essentially, I would be replacing multiple rows with one row which would have the totals (mentioned above). Is this even possible?? If someone could just help point me in the right direction, I would appreciate it.
