unknown number of inputs

I have a script with $_POST and <form> to load data with text input. Situation: enter name of author(s) for book. I have the script set up to enter first_name, last_name for Author1 and the same for Author 2. Check if entry 1 exists then proceed accordingly Check if entry 2 exists then proceed accordingly. Now, If I have three or more authors to enter, is there a way to add a radio button to add more rows for input or to skip further inputs, if I have to enter the inputs for each additional author? I'm looking for a simple way to do this. Could or should Ajax be involved in this somehow? -- unheralded genius: "A clean desk is the sign of a dull mind.
