I want to create a string group-<vari1>-<var2>@thing.com. What I’ve got in expression builder is (‘group-{{R1.group}}-{{R2.role}}@thing.com’) but the output is group-’<var1>’-’<var2’@thing.com what I want is group-<vari1>-<var2>@thing.com. How do I change the expression to get the desired output?

I found a way to do this but it is very cumbersome:

concat(concat(concat(concat('group-','{{R1.group}}),'-'),'{{R2.role}}'),'@thing.com')

that outputs:

group-<vari1>-<var2>@thing.com
There must be a more elegant way to do this...


I was about to say using substring but it’s messy as well. 


That’s the best way, but it’s not elegant.
