// Your first steps could be to read through the tasks, and create
// these functions with their correct parameter lists and return types.
// The function body only needs to contain panic("").
//
// This will make the tests compile, but they will fail.
// You can then implement the function logic one by one and see
// an increasing number of tests passing as you implement more
// functionality

Add Secret Ingredient doesnt go through test. What's the problem?

doesn't work

The type parameters for the function are slightly wrong. Start with fixing that. The instructions for the exercise provide an example on how the function will be used - pay attention to the types of the arguments being passed in and their types. With that you can infer the type of the parameters your function should take.

Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:

for number in range(10):
    total += number;
