Inserting text with an If expressions and dynamic content

Hi All,

I'm making a flow where a Planner task is built when a Form response is submitted. The form has a feield for the given and surname of client 1 and then client 2.

I want to name the Planner task as [Client 1 Surname] & [Client 2 Surname]. 
However, sometimes the there will only be one client completing the form.

I'm trying to get a variable to insert the '&' only if there is a value in [Client 2 Surname]. If I just type '&' between the dynamic content for the two surnames, it will look unfinished and people will think something is missing.

I tried a variable with and if(equals) but I get nothing but errros so this is over my head.

Would appreciate any help you can provide.

Hi @MrNPP,

You could use a combination of if, not, empty and concat functions.


Below is an example:

First check the content of the questions are both not empty. 





Use an and to combine the two checks for both questions.





Use an if to concatenate when true. When true concat with &. When false concat without &.


if(expression, iftrue, iffalse)



All together in one expression:


if(and(not(empty(outputs('Get_response_details')?['body/rc967dd6f6e95478da8f0d470ea418406'])),not(empty(outputs('Get_response_details')?['body/rbf2a89d1c4d0482c840c06a7df4f1a6d']))), concat(outputs('Get_response_details')?['body/rc967dd6f6e95478da8f0d470ea418406'], ' & ', outputs('Get_response_details')?['body/rbf2a89d1c4d0482c840c06a7df4f1a6d']), concat(outputs('Get_response_details')?['body/rc967dd6f6e95478da8f0d470ea418406'],outputs('Get_response_details')?['body/rbf2a89d1c4d0482c840c06a7df4f1a6d']))
