Display message action using variables is not displaying variable text value

The flow I am building is setting a text variable and then I use that variable in a Display message action. I've tried several options, but am not able to get it to work according to what Microsoft documentation is telling me to do. 


Microsoft says to do this:


If I want a phrase in the "Message to display" field to include the variable value. Microsoft says to use %VariableName% but this is not working. Example is "This is the folder %EFGraphEXT%" The result I am getting is the text of "%VariableName%" and not the text value of the variable set, such as the variable value should be "This is the folder _EF-Graph".


If I only have the variable name from the {x} option on the right of the input box, it will show the value, but documentation says I should be able to add more text. 

This does not work, but should



This works without being able to add more text. 



Any ideas?

Hi @rkapofu 

Have you enabled power fx 

Without enabling power fx you will get the value as instructed in documentation 

Once disable power fx in a new flow and create the flow 


Hope this helps

As @UshaJyothi20 correctly pointed out, this is because your flow has Power Fx enabled. The documentation you referenced assumes you did not do that. The syntax is completely different when Power Fx is enabled. 


If you want to keep using Power Fx, try doing this in your message box:

=Concatenate('This is the folder ',EFGraphEXT,' where it is stored.')


The concatenate() function is designed to concatenate separate strings. So, you can merge the two strings and the variable value together.


See here for reference on the function:
