Executing code in basic text

Hi, I’m trying to display a date that has been modified slightly ( 30 days added to it ).
However I can’t get it to execute and display the output. It just displays the code.

Using a basic text element.
Code is echo date(‘Y-m-d’, strtotime(“+30 days”));

any idea what I’m doing wrong?

Thanks, I’d actually already found that but it doesn’t address my question -
How do I get that to execute in a Bricks Basic Text element and so display the result on a page?

create your own function and use it as {echo:date_30}
