I am not sure what is going on here. I even 'got code' from system but that won't give me the check mark I'm seeking. Error message reads, "Add a Category Column" although Category is already in the statement's out put. Help Please!
when 'kale-smoothie' then 'smoothie'
when 'banana-smoothie' then 'smoothie'
when 'orange-juice' then 'drink'
when 'soda' then 'drink'
when 'blt' then 'sandwich'
when 'grilled-cheese' then 'sandwich'
when 'tikka-masala' then 'dinner'
when 'chicken-parm' then 'dinner'
end as category, round(1.0 * sum(amount_paid) /
(select sum(amount_paid) from order_items) * 100, 2) as pct
group by 1
order by 2 desc;
