Hi Ross,
Thanks for the info. I initially thought with Combine I might have to change all the files and not just the master or parameter file but in testing I found as you said just the main initial file will work.
I will also look into what Paul said earlier and creating another query to find the new columns added as looking for the new columns is tedious. I have like 40 columns and
half of them I have the query deleting.
Thanks,
Richard
