You can delete the {{ }} brackets. This is mostly used only when copying and pasting the code from elsewhere.
You can manually type the search function this way:
search(
Then the editor will replace it with the proper formatting with the start and end brackets ( )
You can also select the function from the variables panel.
I would suggest completing the Make Academy before jumping into building a complete scenario.
Hope this helps! Let me know if there are any further questions or issues.
