Works in X Code, not in code challenge... Sorta

What am I missing here? Inputting the following into XCode works, as long as I've given values to variables a and b. If I don't define a and b, it doesn't work in either XCode or the code challenge. Thanks!

float addTwo(float a,float b); {
    float a = 1;
    float b = 2;
    float result = a + b;
    printf("%f\n",result);
}

the reason its not working unless you define a and b is probably

float addTwo(float a,float b); {

that semi colon does not go there.

you are supposed to write a function that returns a float and takes 2 floats as parameters. It should return the sum of the 2 parameters passed in. you dont have to assign any values or print anything out. you also have a semicolon where you dont need one.

This should help:

float addTwo(float a, float b) {

     return 
}

There is a mathematical expression that needs to go after the word return. ill let you figure that out. be sure you end the statement with a semicolon.

I was seriously overcomplicating it. Got it now. Thanks!
