Unfortunately, I can interpret your description several different ways, each of which would take a very different solution. Could you post a link (preferably to the entire base, read-only, with copying enabled) to however much of the base you have been able to complete, with a description of what it still doesn’t do? Feel free to make a copy of it first and strip it down to, say, five records’ worth of dummy or redacted data. If that’s not possible, you can send the link directly to me via private message (click my name and then click ‘message’); it may take a little longer to receive a reply, but I’ll keep your data private.
