First a little background explanation of what I am working on:
I have created a SharePoint Online TeamSite with the purpose of facilitating the offboarding of certain employees.
Once it has been made known that an employee is leaving the institution a person has been designated to fill out an offboarding initialization form which collects the employee name, and exit date. Once this has been submitted it kicks off an email to the offboarding employee with a link to a survey they need to complete. Since this is often ignored we want to send a reminder email every 5 days until the survey has been completed (or their exit date has passed). Right now the reminder emails will work as intended, but after the survey has been completed it will continue to send reminders.
I have added a column to the Offboard Initialization list called "PI Survey Complete" which is defaulted to 'no', but I would like this to be updated to 'yes' as soon as the employee completes their survey. In order to accomplish this, I made another Flow that should update the initialization list item that includes the same email address as the person completing the survey. Here are screenshots of what I have so far.


and here is the other Flow that is actually sending the email reminders:

I feel like the problem lies in the first screenshot under the "Filter Query" field. This is where I believe I need to connect the item from the 'Offboard Initiation' list to the 'PI Offboard Survey' item but I think I am not using the correct syntax.
Thanks in advance for any help or suggestions.
