Just a quick reminder:

Comparing for equality is done by == 
1 == 2 // false 
10 == 10 // true 

Variable assignment is done by a single =
var someString = "hello"

Maybe you meant to compare results with 0 like this:
results == 0

You are assigning instead of comparing by checking for equality.

You wrote:

// Task 2 - Enter your code below

let isPerfectMultiple  = results = 0

Whereas, it should be:

// Task 2 - Enter your code below

let isPerfectMultiple = results == 0
