InfoPath Dev

I have an InfoPath 2013 web form.  On it I am setting a field for secretaryemail.  I also set a field we will call mailto that concat('mailto:', secretaryemail).  I then add a hyperlink on the form and set the "Link To" to the mailto field in the datasource.

When I preview the form and select a secretary it sets the secretaryemail field and the mailto field.  The hyperlink becomes nonclickable and does not act like a hyperlink.

 If I hard code a value in the mailto field it works fine. 

 Anyone have any brilliant ideas?  I'm about to pull my hair out! 

Are you using a hyperlink control or the hyperlink option under the insert menu? Feel free to attach a copy of your form under the options tab in a reply if you'd like me to take a look at it.

 Sorry, I didn't get back to you.  When I published the form it worked fine.  Just not in designer.  Ugh!
