Adding a dynamic hyperlink to your Nintex Form can make it convenient for the end-user to view a relevant item or document. 

For example: An organization is using Nintex Forms on a Document Library. When end-users view the properties of a document the document name is a string by default. To make it convenient for the end-user to view the document from the document properties page, you can add, or replace the document title with, a hyperlink that is dynamically generated by using references.

-On your Nintex Form, place a 'Label' control on your form (or any control that supports Rich Text).
-Access the Control Settings for the Label.
-Place your cursor in the text box to populate further options, click the 'Insert' tab in the top ribbon.
-Select 'Link'.
-In the Insert Reference window, select the 'Common' tab.
-Configure the fields as follows:-Click 'Save' in the top left under the 'General' tab.
-Publish the form.

The result is as follows:

If you are attempting to add a hyperlink using this method on a Responsive Form, it may be necessary to hard-code, the reference to achieve the same result.
