String is not registering

https://www.codecademy.com/paths/web-development/tracks/getting-started-with-javascript/modules/code-challenge-javascript-fundamentals/lessons/javascript-fundamentals-code-challenge/exercises/reporting-for-duty

im trying to complete a string but for some reason its not accepting the quote marks.

By string parameter, it doesn’t mean string as parameters, but parameters that will have the value of a string passed into them.

That means that they are normal variables, just like any other parameter type, however you treat them like a string in the function.

const someStrFunction = (string1, string2) => {
string1.toUpperCase();
return string1 + string2;
}

See here, they are normal variable like parameters, but I am treating them as strings.
I hope this helps!

Hi, sorry I speak poor English
You must define rank and lastName as parameters of the function. No 2 empty strings, then you don’t need to add “+” on your return declaration because your return declaration is surrounded by template literal, so everything inside will be considered as text, except your variable included in $ {variable}
