in reply to Assign perl value in html link

I want to have <a href> link next every variable saying EDIT and give them ability to change it before submitting the form.

Treat editing as another form submission that you have to carry all of the variables through, except in this case the only variable visible to the user is the one they're editing (all others are hidden). To return to the previous page you'll need to either encode that page as an argument to the CGI the edit form submits to, or use a hidden field to hold the URL, and rely on the CGI to redirect to it.

This'll require that you have an edit button instead of a link.

    The tricky part is I dont really want to create a separe page for each field because i have over 20 of them.
    I guess I can carry on all the hidden variables to edit page and also have this: <input name="edit" type="hidden" id="edit" value="[company]">
    ...BUT.... I can't figure out, how I would assign to what varibale [edit] needs to be assigned. How can I make EDIT equal to the varibale user wants to change, and then when they return to confirmation page how I make that field equal to EDIT?

      You can probably get by with a small number of generic edit pages, depending on the type of data you'll be editing. (If everyhing can be editing in a 20 character field, you can use a single edit page).

      Here's how it works: You already have a form that contains some number of visible and invisible fields. Add alternate "Submit" buttons labeled "Edit". Give these buttons the name of the field you want to edit (or some name from which the target field name can be derived).

      When one of these buttons is pressed, it submits the form. The CGI that catches the submit needs to recognize that an edit button was pressed (as opposed to an "I'm done with this page" button), and respond by producing an HTML page that includes a form. The form has an edit field for the field being editing, and all other form values hidden. The form action for this page is a CGI that handles the edit, and redirects back to something that will regenerate the page you started out on (e.g., your "confirmation" page).

        So there's no way I could write in JavaScript something like that to make it work? 
        <a href="javascript:edit=formname.company">
