Working with CCK, I've gone ahead and created a new node type with all the fields, themed the form, etc. I have a select list that users must choose from to submit the form. This select list contains a list of my clients. What I need to do is store data on each one of those clients and use that when processing the form.

Here's my select list example:
105|Los Angeles, CA
120|Sacramento, CA
810|San Diego, CA
100|Walnut Creek, CA

Depending on what client is selected, I need to send an email to that location. Most (if not all) of my locations have multiple email addresses, so I need to come up with a way to dispatch an email to the correct stored addresses.

In summary, what is the best method to store information (My clients email addresses) in the database that can be pulled and managed easily according to my select list?
