Hello,
I am trying to build a flow identical to the forum here.
https://powerusers.microsoft.com/t5/General-Power-Automate/Send-automated-email-using-a-spreadsheet-saved-in-sharepoint/td-p/336939
However, I keep getting the following error message.

Since I have built the Flow identical to the one in the forum, I do not understand where I am going wrong. My Flow is as follows



As someone who is a total newbie to Power Automate, can someone please advise me on how to fix this?
Thanks in advance!
Adam
