How can I add a standing Charge, like freight into the form and have it included in the total.

For now, the only workaround is to add freight as a product in your order form, then have it preselected using URL parameters - such as in this example:

http://www.jotform.co/form/20657572945867?myProducts1[][id]=1011

If you have the form embedded in a page, simply append the parameters to the URL of the form in the embed codes.

For example:

<script type="text/javascript" src="//support.interlogy.com/jsform/20657572945867?myProducts1[][id]=1011"></script>

It may not be a foolproof solution but this is all we have until our developers can work on something more viable.

We will update you in case a feature such as that is implemented.
