Hi Everyone,

Thanks in advance for the support solving my error below and this great service - Love Mrexcel ;-)

I have a UDF being called from an .xlsm file. It is defined as follows:

Public Function LookupExternalData( _
ByVal FilePath As String, _
ByVal ProjectArray As Range, _
ByVal ColumnArray As Range) _
As Variant

The first time I call the function it works and returns values in the .xlsm (array of 4 by 49 values). The function call is as follows:

=LookupExternalData(CQ13,$A$17:$A$66, CQ15:CT15)

where

CQ13 = C:\Users\E100465\OneDrive - RMIT University\PIR\Projects due to close\Projects due to close in 2021 - 121Apr2021.xlsx
$A$17:$A$66 = range of values shown at the end of post
CQ15:CT15 = {52,67,4,8}

The problem comes when I attempt the same function call with different parameters, it returns "#SPHILL!" (My name in Simon Phillips).

The second function call is as follows:

=LookupExternalData(CM13,$A$17:$A$66, CM15:CP15)

where

CM13 = C:\Users\E100465\OneDrive - RMIT University\PIR\Projects due to close\Projects due to close in 2021 - 25Mar2021.xlsx
$A$17:$A$66 = range of values shown at the end of post
CM15:CP15 = {52,67,4,8}

I have stepped through the debugger in VBA and there are no errors thrown. Prior to function exit I can see that the LookupExternalData array is correctly filled out in the watches


I cannot understand what is different in the 2 files being referenced (CQ13 versus CM13) and why the UDF fails in the second case.

Excel Facts

What is the shortcut key for Format Selection?
Ctrl+1 (the number one) will open the Format dialog for whatever is selected.
In the cell where you make the second UDF call, is there room below and to the right to display the results, i.e. 50 rows and 4 columns of non-blank cells (i.e. apart from the formula cell)?

If any of these cells are not blank, you'll get a #SPILL! error.

Thanks Stephen - I could not "see" anything but I did a "Clear Contents" and it now all seems to be working !

I am so grateful for your generous support
