Hi there tanmay sharma! To remove the items from a list the code needs to be outside the definition of the states array. And we do this like so:

states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
]
states.remove(5)
states.remove(['red', 'green', 'blue'])

The first states.remove will remove the 5. 5 is not a string, nor is it part of an array inside of an array, so only the 5 is needed inside the parentheses. The second states.remove line needs the brackets inside the parentheses as we're removing an array from inside an array. Hope this helps! :sparkles:

I think you have to perform states.remove() on a separate line. Also, it's worth noting that workspaces can be buggy. Sometimes try saving and reloading the page.
