Within a macro written using Visual Basic, I use the .Delete or
..ClearContents method to erase a range. When I call the macro from the
immediate window, it always works. When I call the macro from within the
workbook, it usually does not work. (I have seen occassions that work, but I
have not identified a pattern.) The place the macro is called is on a
different worksheet from where the range to be deleted resides. I have not
turned on any protection modes.

Nice to post your macro for comments

If you mean you have a formula that calls your VBA function, a UDF, it will
never work as it can only return a value. It cannot change the interface in
any way such as erase a range. A least not without writing your UDF in a
rather unusual way!

I think you would be much better off using dataimport external datanewput
in your urlimport.
Then record a macro while doing. Then modify to put into a loop and copy
desired data from the fetch sheet to another sheet with just the data you
want. Send a workbook to my address below with your symbols, etc and I will
take a look.

Regardless of how i import the data, I want to erase the previous data
automatically. Try this with a new workbook:
Type text into cell A1.
Add this macro into module -
Function EraseA1() As Boolean

If (ActiveSheet.Cells(1, 1) < Empty) Then
ActiveSheet.Cells(1, 1).Delete
End If
If (ActiveSheet.Cells(1, 1) < Empty) Then
EraseA1 = False
Else
EraseA1 = True
End If
End Function

Now in another cell on the same worksheet use the formula =EraseA1(). The
result is FALSE.
Now in the immediate window type x = EraseA1(), and Cell A1 on the worksheet
gets erased.

What am I missing?

All you need to do is set up a query ONE time and refresh( vs delete and
re-create) using this which will automatically get the data for the symbol
and times desired. If you send me your private email to my email below I
will send you a workbook.

'Goes in the SHEET module
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address < "$A$1" Then Exit Sub
sym = Target ' Range("a1") 'ibm
mdate = Range("a2") '2008-03
With ActiveSheet.QueryTables(1)
.Connection = "URL;http://finance.yahoo.com/q/os?s=" & sym & "&m=" &
mdate
.Refresh BackgroundQuery:=False
End With
End Sub
Calls Strike Puts
