    Hi,
     
    This is happening because the properties for the Form answer for questions questions Full Name and Arrival Date don't match perfectly to the question text. For example, in the following image, a response to a question with the text "Please enter your email" is read by Power Automate via its unique identifier:
     
    An easy solution for that is to work with the dynamic contents, and you can use them even within your expressions. Type your expression, and then allocate your mouse cursor between the expression parenthesis. After that, click in Dynamic content tab (highlighted in yellow):
     
    And then select the desired question that you want to reference. In the example below, I selected the First name question, which generated an expression (highlighted in yellow) much different from its display name: 
     
    Next I added a comma and the dynamic content from Last name question: 
     
    After running the flow, this is the outcome (there is no blank space between first and last name because I was lazy when writing the concat() formula):
     
     
     
    Also, if you want to read further on this topic, I wrote an article about dynamic contents in Power Automate some months ago that covers this exact example (pulling data from MS Forms and writing into Excel table): http://digitalmill.net/2023/07/31/using-dynamic-content-in-power-automate/
     
    Let me know if it works for you or if you need any additional help!
