Excel with scripting in it

Hi. I am trying to embed some scripting that I have in an excel file, but I am not able to do that.

That's an example:

^isEU()?"</p>In accordance with GDPR, the data controllers for XYZ project will be named at the end of the interview.":""^

I am trying to create placeholders out of ^isEU()? and :""^ but the embedded option in Trados does not work (I did hit "Include" in the Advanced options). Anyone know as to why it does not work? Thanks
