        <div>It was originally designed to allow access to the jos_users table to create member
        profiles but it is capable of much more.</div>
        <div>To use the plugin effectively you will need to call the form from a link on your site.
        This could be from - for example a list of users, or topics, or events where you have
        some related information in a database table.</div>
        <ul><li>Choose the table you want to use in the first drop-down
        e.g. jos_users to get a user's name and email.</li>
        <li>Select a field or column name from the table in the second drop down.
        This should be a field that will uniquely identify the record you want to use
        e.g. 'id' or 'username' for the jos_user table. NB This drop-down will not appear
        until you select a table in the first drop-down.</li>
        <li>In the Target field name box put the name of the field you will use to identify the
        record e.g. user_id. You will need to add this field to a url calling the form
        e.g. . . . &chronoformname=my_form&user_id=99 </li>
        <li>You can then use information from this record in your form by putting {column_name} where
        you want it to appear e.g. {name} for a users name from the jos_users table.</li>
        <li>Once this plugin is configured you must enable it in the Form 'Plugins'' tab.</li></ul>
