Need some help on Codecademy.com

Hello there, i'm on codecadyme at the JavaScript Quick Guide, but i'm stuck in this one:

http://www.codecademy.com/courses/javascript-intro/3#!/exercises/7

this is what i have to do:

// Example switch statement. typeof returns the type // of the value as a string. For example, the type of // a string is 'string', the type of a number is // 'number', and the type of an object is 'object'. switch (typeof 'foo') { case 'string': // some code

    // If you don't return in the block, you should
    // always have a break afterwards.
    break;
  default:
    //block

}

// Write a function that uses switch statements on the // type of value. If it is a string, return 'str'. If it // is a number, return 'num'. If it is an object, return // 'obj'. If it is anything else, return 'other'.

and this is what i did : function detectType(value) {

switch (typeof value) { case 'string': return 'str' ; }

switch (typeof value) { case 'number': return 'num'; }

switch (typeof value) { case 'objet': return 'obj'; } default: return "other"; } return value;

}

</> I'm a noob, so i don't know whats missing or wrong, would you kind people please help me? thank you.
