        <div>The plugin allows you to use the PHP CURL function to send data from a ChronoForms Form to
        another site or to another application on your site. Use this when you need to keep flow control
        with ChronoForms so that a ReDirect URL will not work correctly.</div>
        <ul><li>First, open the CURL params tab and put the url that you want to submit the information to
        in the Target URL box e.g. http://crm.zoho.com/crm/WebToLead </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>For testing, set debugging on the CURL params tab to Yes and you will see a debug report after your form is submitted.</li>
        <li>Lastly on the CURL params tab, you can set the CURL to run before or after Emails are sent.
        Use this if you need to fine-tune the process flow.</li>
        <li>The Extra Code tab allows you to add extra PHP to run before or after the CURL transaction.
        Normally you will leave these boxes empty; use them if you need to alter the submitted data in some way.</li>
