From swap-menu to database

I have a swap-menu in a form that includes two multiple-selectboxes and two buttons for moving data between the boxes, and that works just fine. Now, when I press the submit-button, I want to take the data from selectbox no.2 into first a script that checks that it is something in the box at all and then forward into the database. I don´t want it to matter if the data in the selectbox are selected or not. I want it forward anyway....
Has anyone done this before? How can I do this?

Please help

Well, just do some sort of validation routine:

function Validate() {

    if (document.theForm.selectbox.value) {
    return true;
****}
****else {
********return false;
****}
}

Now that selectbox.value bit is not the right way to address the variable, but it is just an example. Now, to make your script use this function, alter your <form> tag:

<form method=POST action="your.cgi" onSubmit="return Validate()">

Then write a perl script or something to handle your data, once it gets there.
