Custom Item in "AddRow_Excel"

How can I get a specific Excel table based on contents derived from previous actions? PowerAutomate in fact gives the possibility to write a "custom element", but I don't know how to do it and it doesn't even indicate which language to use. The tables in my Excel file are renamed as Name_Surname, so I tried with the dynamic content from the previous steps (DynamicContentName-DynamicContentSurname), but it can't detect the corresponding table.

Hi @Arianna,


Do you want to add a row to a table and the filename and table name are dynamical? If so, you could following these steps:

Sorry, I explained wrongly the problem. I know how to work with dyamic content but in my case I need to retrieve a table based on the Name I enter in the action "Trigger manually a flux". PowerAutomate gives the possibily to add a customized content for the table, but I dont know how to write it because with the dynamic content it doesnt work even though the input shown in the screenshot is correct! 

The error is "The request entity's media type 'text/plain' is not supported for this resource." 

I hope the images help to understand the problem 😞
