Adding info to 2 tables

[tequilacat]

I'm trying to figure out how to add info to two tables in the same database. Here's what I want to do:

First, folks will enter business information into a form. This info is inserted into a table.

Next, they enter more information about thier business, which I want to go into a different table.

I need to match a key up with both tables so that business A in the first table matches up with business A info in the second table.

I think the way to do this is to use sessions, but I'm having troulbe figuring all of this out. Any suggestions would be greatly appreciated!

Thanks,
tequilacat

since you need a unique value for to link, if you don't want to use sessions, you could use time & datestamp
