The question is not very clear. When you say insert
columns, it looks like you actually mean rows.
The output doesn't seem to match the input. Are you
saying that if a date appears where lpc-b has a value n,
then that dat eshould appear n times? 1/1/92 has a value
5, and is already once in the results file, so add four
more. 1/2/92 has a value 0, so its removed from the
results file. dates in the result sfile that aren't in
the source file, like 11/29/91 are left in situ.

proposed methodology:
For each date in the source file, count existing items,
adding or removing as required



Sub DateGrind()
Dim wsSource As Worksheet
Dim wsResults As Worksheet
Dim SourceRow As Long ' row pointer for Source book
Dim ResultRow As Long ' row pointer for Result book
Dim count As Long ' for counting the dates
Dim ThisDate As Date ' date to be tested
Dim RequiredCount As Long ' lpc-b number

' point to the relevant sheets
' note the data is as per the question
Set wsResults = Workbooks("Book2").ActiveSheet
Set wsSource = Workbooks("Book1").ActiveSheet

SourceRow = 2 ' row 1 is headers : date/lpc-b

Do Until wsSource.Cells(SourceRow, 1).Value = ""

ThisDate = wsSource.Cells(SourceRow, 1).Value
RequiredCount = _
wsSource.Cells(SourceRow, 1).Offset(0, 1).Value
count = 0
ResultRow = 1

Do Until wsResults.Cells(ResultRow, 1).Value = ""

If wsResults.Cells(ResultRow, 1).Value = _
ThisDate Then

count = count + 1
If count RequiredCount Then
wsResults.Rows(ResultRow).Delete
Else
ResultRow = _
ResultRow + 1
End If
Else

ResultRow = ResultRow + 1


End If
Loop

Do While count < RequiredCount
wsResults.Cells(ResultRow, 1).Value = ThisDate
ResultRow = ResultRow + 1
count = count + 1
Loop

SourceRow = SourceRow + 1

Loop

End Sub


Basically the outer loop refers to each date in the
source.
the first inner loop counts the matching dates - when the
count exceeds the requirement, dates are removed. the
second inner loop adds dates if the count is less than
the requirement.

I am trying to use the lpc-b dat in testsource.exl to
expand the date column
in testresult.excel, inserting blank columns and then
filling down so the
number of date entries equals the lpc-b value. final
spreadsheet should look
like this:

file:testresult.exl
date
11/29/1991
12/24/1992
1/1/1992
1/1/1992
1/1/1992
1/1/1992
1/1/1992
1/3/1992
1/4/1992
1/4/1992
1/4/1992
1/4/1992
1/5/1992
1/6/1992

I found that when I record a macro, the operations of
moving one column down
and dragging down to select a range of cells don't seem
to be recognized
and, indeed, when I try to modify the macro to do this I
get error messages
about procedures not being supported. Is it possible to
fix the following
code, or is it not possible to do using variable names.
Commented code
follows:

Sub Macro1()
'
' Macro1 Macro
' Macro recorded 7/22/03 by Thomas L. Wright

Workbooks.Open FileName:= _
"Macintosh HD:TLW/RSF kilauea
book:tilt/seismicity:tilt/seismicity.excel:eq
count/tremor:testsource.exl"
Workbooks.Open FileName:= _
"Macintosh HD:TLW/RSF kilauea
book:tilt/seismicity:tilt/seismicity.excel:eq
count/tremor:testresult.exl"
Windows("testsource.exl").Activate
Range("d2").Select
Selection.Copy
eqctnum = Selection
Range("A2").Select
Selection.Copy
sourcedate = Selection
Windows("testresult.exl").Activate
Columns("A:A").Select
Selection.Find(What:=sourcedate, After:=ActiveCell,
LookIn:=xlFormulas,
LookAt:=xlPart, SearchOrder:=xlByRows,
SearchDirection:=xlNext, _
MatchCase:=False).Activate
ActiveCell.Select
Code works to here, including use of
variable for date
now when I try to move down one
cell, select that cell
and the three below it, no command, wuch as cell.offset,
seems to work
Selection.Insert
Shift:=xlDown This line works
Windows("testsource.exl").Activate

The rest of the code uses explicit
ranges, which I
cannot specify without using the variable "eqctnum".

Range("A3").Select
Application.CutCopyMode = False
Selection.Copy
Windows("testresult.exl").Activate
Columns("A:A").Select
Selection.Find(What:="1/2/1992", After:=ActiveCell,
LookIn:=xlFormulas,
_
LookAt:=xlPart, SearchOrder:=xlByRows,
SearchDirection:=xlNext, _
MatchCase:=False).Activate
Application.CutCopyMode = False
Range("A9").Select
Application.CutCopyMode = False
Selection.Delete Shift:=xlUp
Windows("testsource.exl").Activate
Range("A5").Select
Windows("testresult.exl").Activate
Columns("A:A").Select
Selection.Find(What:="1/4/1992", After:=ActiveCell,
LookIn:=xlFormulas,
_
LookAt:=xlPart, SearchOrder:=xlByRows,
SearchDirection:=xlNext, _
MatchCase:=False).Activate
Range("A11:A13").Select
Selection.Insert Shift:=xlDown
Range("A10:A13").Select
Selection.FillDown
Range("B9").Select
ActiveWorkbook.Save
ActiveWindow.Close
Range("B4").Select
ActiveWorkbook.Save
ActiveWindow.Close
End Sub
