Hi there! I can only assume that you are working on step 2 as your code passes Step 1 just fine. However, in Step 2 it says to turn them into floats before you add them. Remember, you have no idea what they're sending in. They might send in 21 and "Hello!". One can be converted to a float, but the other one can't.

Here's what my return statement would look like for Step 2:

return float(num1) + float(num2)

This code takes each number individually and turns it into a float (or fails with a ValueError) then it adds them and returns the result.

Hope this helps! :sparkles:
