    In a table in which there is more than one primary key (using php3):...

    I want to create a php script that displays say (for the purpose of adding to database):
    Customer Id # (as a select)
    Email (as a select)
    two other fields

    a customer may have more than 1 email, but each email is unique as is the customer id #

    i know how to populate the customer id # from the database but is there a way (without creating a new script and passing it customer id # (storing it as hidden in the next scripts form, and then limit the emails listed)) to disable the email select until the customer id # has been selected (which then populates the email select and enables it)

    in other words is there a way to do this in 1 script?

    You'll have to look into Javascript to accomplish that. The Javascript works client-side, so you could create a script to make the E-Mail field become active when you select a customer ID... The most I do with JS is cheap AM/PM clocks and fancy image mouseover/out stuff, so I'd suggest you take a visit over to the DevShed Javascript forum.
