If your Wufoo form is not showing on the page in your Sitebuilder, there are a few reasons why this might be happening.
First, make sure that you have copied and pasted the entire block of code that Wufoo has given you, and once this is done click the Refresh button which is located right next to the Save button. This should make the form visible on your page, and you can then click the Publish button to make the changes to your site live.
If this does not help, please get in touch with the Customer Service team and let us know.
