Hi
As part of an application, I need to intereract with another (in-house)
application's data, so therefore I cannot change the layout of this
data. This data is stored in delimited text files on a network folder.
Basically, each time a new figure becomes available, a new figure
(month) is added to the appropriate text file which, for each line has
13 delimited columns (a year and 12 months) by as many rows as there is
data available.

The text file looks like this:

1963, 3.8, 3.8, 3.8, 3.9, 3.9, 3.9, 3.9, 3.9, 3.9, 3.9, 4.0,

Martin,

You never store the last available value properly. Change:

Input #FileNo, IndDate, IndValue(1), IndValue(2), _
IndValue(3), IndValue(4), IndValue(5), IndValue(6), _
IndValue(7), IndValue(8), IndValue(9), IndValue(10), _
IndValue(11), IndValue(12)

If EOF(FileNo) Then
For IndCounter = 1 To 12 Step 1
If CDbl(IndValue(IndCounter)) = 0 Then
LastAvailableValue = IndValue(IndCounter - 1)
Exit For
End If
Next IndCounter

If CInt(IndDate) <= Year(DateToLookFor) Then _
IndValue(Month(DateToLookFor)) = LastAvailableValue
Exit Do
End If

To:

Input #FileNo, IndDate, IndValue(1), IndValue(2), _
IndValue(3), IndValue(4), IndValue(5), IndValue(6), _
IndValue(7), IndValue(8), IndValue(9), IndValue(10), _
IndValue(11), IndValue(12)

LastAvailableValue = CDbl(IndValue(12))
For IndCounter = 1 To 12 Step 1
If CDbl(IndValue(IndCounter)) = 0 Then
LastAvailableValue = IndValue(IndCounter - 1)
Exit For
End If
Next IndCounter

If EOF(FileNo) Then
If CInt(IndDate) <= Year(DateToLookFor) Then _
IndValue(Month(DateToLookFor)) = LastAvailableValue
Exit Do
End If

Hi
As part of an application, I need to intereract with another (in-house)
application's data, so therefore I cannot change the layout of this
data. This data is stored in delimited text files on a network folder.
Basically, each time a new figure becomes available, a new figure

13 delimited columns (a year and 12 months) by as many rows as there is

The idea is the user enters a date into a userform, that date is then
passed to my code below and this returns the figure for the year and

I'm having is where the month required is 01/04 but the last available
yield is 12/03. It's probably really straightforward to change, but I
just can't get my head around what needs to change. So with the above
data, if the date "31/01/2004" is passed to the procedure, it would
return 76.8 (the latest available figure) (the same would apply for any
date in the future), yet if "30/06/2003" was passed, then it would
