Answer
How to add hyperlink in Calculated value?
+4Best answer by jpmhuls
Hi Joe Lau,
Look closely to the example formula in the link you mentioned:
"<a href=""http://www.mydomain.com/user=" + varAppendToLink + """> click here </a>"
The double quotes within a text between double quotes, in this case enclosing the URL, need to be specified with a backslash in front (marked in bold and red). So your formula should be:
"<a href=""http://www.yahoo.com.hk"">Testing</a>"
NB: The blog editor puts a link symbol behind .com.hk which you need to ignore as it is not part of the string.

Thanks for posting this.It worked a treat for me on the browser but it doesn't render on Nintex mobile apps 
As you can see above - the Calculated control don't seem to render HTML on the mobile app. The only control I found that could render HTML is Rich Text, but I can't find a way to dynamically set a link in Rich Text, based on input values from other controls.
Use case: I need to embed a deep link on one form to send users to another form. At the same time, passing form values to pre-populate the "destination" form (using parameters in embedded deep link).
Note: I am constraint to Responsive form in Nintex for Office 365 in this case.
Any help would be greatly appreciated!
