just have the information emailed as a comma delimited string and then Access can handle that without issues
"have to follow his wishes".. realize that customers are not web programers and sometimes what they seem is feasible/possible in fact is not either....... you need to learn how to handle your clients better because look at what is happening... you are way over your head (in this thread and in many past threads of yours)
personally, i'd save the info in the database and maybe just email his the database now and then (as long as it didn't get out of control size-wise)
