Decisioning offer in code base

Could somebody tell me what is wrong with this syntax? This is decisioning in code base channel. 

I did what is said in the documentation and it did not work. I asked support and they are working on this for two weeks and this still does not work 😍😍

When I render this on the webpage there is fatal error

Any ideas??
