Linking Related (But Non-Identical) Fields?

Hi,

I have a form that has some related (but non-identical) fields, for example: name, signature, telephone number and email.

When, for example, "John Smith" is entered into the name field, I'd like "/John Smith/" to populate the signature field, and John Smith's telephone number and email address to populate *those* fields.

When "Mary Brown" is entered into the name field, I'd like *her* information to populate the same fields. How do I accomplish this?

Many thanks in advance for your help!
