I'm not sure whether it would be breaching any Forum guidelines, but I would like to pick up on this thread which Graham Mayor solved for me just over a year ago.

I am trying to modify the Process actions in order to link some different files. The original solution has worked very well. But what I now need is to modify the code so that 3 fields (not just 1) in the 2 files ('Bank' and 'Donors') have to be linked. I am unable to trace in the code where the necessary changes need to be made - and I'm not even sure that what I need will be possible!

Am I right in also assuming that the 'Bank' and 'Ledger' files can be the same? In other words I would like to add some data to the 'Bank' file based on information in the 'Donors' file instead of inserting it into the 'Ledger' file.

If you need me to provide the present coding I can do that, but it is in the file that Graham posted in his penultimate message on 26th November.
