How to add a calculator widget to the site?

Hi Mark,

You can use the Custom HTML element described here: https://support.ucraft.com/elements/custom-html

* please note that the element is available on the paid plan!

Hope this helps,

Open your web page in the Google Sites editor. Put the insertion point where you want the calculator to appear and click on Insert > More gadgets… Search for “include iframe”. Click on the Include gadget (iframe) in the list.

Thanks! 

Great!
