You may find while designing your Nintex Form, that you need to include a hyperlink to another location. I'm going to show you how you can add a hyperlink to a label control. It's very similar to adding a hyperlink to say, a Word document.

Now you can add in your hyperlink. Click on the Insert tab, and then click on Link.
This is where you can add a hyperlink into your form.
