    <tr>

        <div>The plugin allows you to use the Redirect URL to send data and the user from a ChronoForms Form to
        another site or to another application on your site. Use this when you need to redirect the user
        for example to PayPal to authorise a payment, if you just want to transfer data from the form and keep teh user on
        your site, then the CURL plugin is better.</div>
        <ul><li>First, open the URL params tab and put the url that you want to submit the information to
        in the Target URL box e.g. http://www.paypal.com/cgi-bin/webscr </li>
        <li>Next click the General Tab and you will see a list of the fields in your form.
        Put the corresponding names for the site you are sending to in the boxes along-side
        (often these will be the same as the field names in your form.)</li>
        <li>In the Extra Fields Data box you can enter values for fields that will be the same
        for each submission. These will often be client or transaction identifiers for the other site.
        (Note: Putting this information here means that it is never exposed in your form.)</li>
        <li>Lastly on the Redirect params tab, you can set the Redirect Plugin to run before or after Emails are sent.
        Use this if you need to fine-tune the process flow. Note that the Redirection will be done after any emails are
        sent and the data saved.</li>
        <li>The Extra Code tab allows you to add extra PHP to run before the Redirection Plugin
        (running code after redirection is not possible).
        Normally you will leave these boxes empty; use them if you need to alter the submitted data in some way.</li>
