TSql Query output  to Excel Spreadsheet generates severe error. Although expected operation completes OK. What's wrong?

I have put together this (attached) Ms SQL script (with a little help from the web) that exports a query to a new excel spreadsheet. The included script was written on my laptop using MS SQL Express, although when tested on my 2003 Server/MSSQL Server SP2 I encountered the exact same error. I have Office 2003 installed locally and Office 2007 installed on server.

I had issues with permissions to the output folder which is the reason it is set to output to the shared directory.

My problem is that whenever the script is run, even though it seems to do everything I had intended it to do, it generates this error;

Quote:
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

With the spreadsheet already in existence with the correct sheet name and so forth the error is not generated. Although the script needs to be able to create the file from scratch as the query needs to be able to be changed dynamically in the future.

I've pinned it down to the line "EXEC @OLEReturnvalue = sp_OAMethod @ADOObjectIdentifier, 'Execute', NULL, @DDL, NULL, 129", and have established an error code of -2147211470 (prints when the code is run). Yet thats as far as I seem to be able to get.

Can anybody see where I  am going wrong?

Thanks,
The link you posted at first confused me because I was not using synonyms which was the cause of the error described but it led me on the right track. I decided to use synonyms, and use them without the "sp_". Works great.
