I have two sheets in my workbook. In sheet 1, Column A (say sellingDate)
has dates and column B (say apples) has some numbers. In sheet 2 I have
column A (say givenFridayDate) where I have dates and column B
(calAverage) where I need to calculate some valve using the UDF.

What I need to do is to have some function that takes givenFridayDate
value and return average of apples sold for sellingDate less than equal
to givenFridayDate and greater than the date that falls 5 days back from
givenFridayDate (i.e. Last sunday).

I don't know how to use Ranges and filter the data that falls within
given dates. Please suggest some solution. Thanks.

You can do this with a formula

=AVERAGE(IF((Sheet1!A1:A20<=Sheet2!A1)*(Sheet1!A1: A20=Sheet2!A1-5),Sheet1!B
1:B20))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.

=sumif(Sheet1!A:A,"<=Feb 24, 2006",Sheet1!B:B)-sumif(Sheet1!A:A,"<Feb 19,

gives the sum

to use the value in A1 for a date

=sumif(Sheet1!A:A,"<="&A1,Sheet1!B:B)-sumif(Sheet1!A:A,"<"&A1,Sheet1!B:B)
gives the sum

for an average
=(sumif(Sheet1!A:A,"<"&A1,Sheet1!B:B)-sumif(Sheet1!A:A,"<"&A1,Sheet1!B:B))/5

I would recommend this over an array formula or sumproduct (which is also an
array formula) if you will be using many such formulas as it will be much
faster to recalculate.

You don't say what doesn't work and then give us pseudo-code, but not that
SUMOF is a worksheet function, to use in VBA try

Application.SUMIF(dateRange, "<=" & (endDate + 2), dataRange)

In real code you use

Set dateRange = Range("CSR!$O$20:$O$351")

Make sure the code is in a general module, not a sheet module, the
thisworkbook module or a userform module. in the VBE, Insert=Module. Put
it in that.

I am having similar problems as described in the original question. I am
trying to create a UDF that runs on one worksheet and internal to the UDF it
collects values from another worksheet. I can make it work when everything
is on one worksheet. But, as soon as I introduce a reference to another
worksheet, the UDF has no result and returns #Value.

For example: I have:

Public Function MyFunction(iAIndex as Integer, iBIndex as Integer) as Variant

Dim a
Dim b

Set a = ThisWorkbook.Worksheets("MyFirstSheet").Range("The ARange") '
TheARange is a 1xN range
Set b = ThisWorkbook.Worksheets("MyReferenceSheet").Range( "TheBRange") '
TheBRange is a 1xM range

MyFunction = TheARange(1, iAIndex) * TheBRange(1,iBIndex)

End Function

Basically, what I have been able to figure out is that as long as the
function is calling a value from the worksheet where it is used, this works.
But, if it tries to touch another worksheet it is broke. Is this a
limitation on the UDF method or am I missing something?

Your help is greatly appreciated.

Best regards,
Mark Bower
