open the console, does it show errors?

[mpaata]

this is what it says
// running tests 1. You should define a

removeSpecialChars

function. 2. Your

removeSpecialChars

should not remove spaces. 3. Your

removeSpecialChars

should remove single quotes. 4. Your

removeSpecialChars

should remove double quotes. 5. Your

removeSpecialChars

should remove underscores. // tests completed

// console output
Uncaught SyntaxError:
Unexpected token 'u', "function pa"... is not valid JSON
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]

[mpaata]

it shows errors and tells me to define the function yet i have already did it

[ILM]

@mpaata

// console output
Uncaught SyntaxError:
Unexpected token 'u', "function pa"... is not valid JSON
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]
[TypeError: removeSpecialChars is not a function]

this is the error I was asking about.
Do you see anything in the console if you don’t run the tests?

can you share all the code you have in the editor? (also outside of the editable region)

[mpaata]

yes i see something like this
Uncaught SyntaxError: Unexpected token ‘u’, “function pa”… is not valid JSON when i don’t run it

[ILM]

can you share all the code you have in the editor? (also outside of the editable region)

[ILM]

thinking about it the error could be from line 13, try to clean your cache and local storage

your code is fine, you need to clean local storage
