Excel 2003 SP3 problem

Hi, I'm at end of tether with Excel. After many a pain in 2007 SP2 to get my database query to work with paramters I found it doesn't work with 2003 SP3. (I cheated on 2007 by using skeleton of an old spreadsheet that did work but still dont understand why what where when but that is a separate issue now which will post another time)

Basically, I now have a stored procedure on my SQL 2000 server that requries two parameters parsed to it. My spreadsheet calls it with command EXEC my_proc value1,value2 If I hard code the 2 values then it works well and likewise, if I simply specify EXEC my_proc ?,? then I am prompted for the paramters which are then parsed and all is well,

However, when I open same workbook in 2003 SP3 I do not get prompted to enter the parameters and am merely told the requried paramters were not provided. When I goto the Data >> Import External Data menu I only have option to edit query or Data range properties, the paramters option is greyed out. This is useless to me. After such a balls ache with 2007 I thought I was home and dry but MickeySoft obviously has other ideas.

Help will be much appreciated.
