Tried this numerous ways. Seems to be a syntax issue...ironically Treehouse has a typo in the error message...parameter

float a=1.1; float b=1.2; float addtwo(float a, float b){

return a+b;};

This should work, unless the return can't add...so I also tried making a float named c...made it equal to a+b...and then returned c....yet that didn't get through either...

Hi Uni,

Your only problem is that you didn't capitalize the 't' in addtwo Your code will pass at that point.

It's not necessary to define the variables.

Your semicolon at the end of the function block will count as an empty statement and isn't necessary to put in.

It's as if you wrote it like this:

float addtwo(float a, float b){
  return a+b;
}
;

You have your function definition and then an empty statement afterwards which doesn't do anything.

Hi Uni,

The challenge is only asking for you to write the function so you don't need the floats declared before it, also you have a semi-colon after your closing brace which will cause a syntax error.

float addTwo(float a, float b) {
  return a + b;
}
