MTM: jQuery code block renders as text not as script

Hello - I’m new to MTM. I’m having an issue with adding a bit of jQuery code via MTM using the Custom HTML feature.

The code I added does not render on the page as code for execution, rather it is visible just like normal text on the page. What did I miss? If I wrap it in tags, MTM doesn’t like it or allow publish.

Thanks for any info/ideas or links to relevant helpful docs.
