Hi

I don't think I am too far off with the report. I have picked up the Taxon Sort order not the Taxonomic Order and this will be easy to fix, as will the Obs comments.

I have made some changes and can run the report in Windows 11 on SQl Server 2017. Can you give it a go please. (Not done obs comment yet). 

If  there is a solution to the original problem I fear it may be a long time coming. Not sure if the steering group would authorise the expenditure or if John van Breda will be willing to take on the work. If I can get you the reports you need then this will give me some breathing space to investigate.
