Well,
I declared the list as a "var" in my main
However it is a function parameter where I have the error
What do I have to do to make sure it stays a "var" and not a "val" ?
(If that is what I have to do, maybe I'm misunderstanding)

A "val" is an "immutable" record of a value. By immutable we mean it
cannot be reassigned. There are lots of positive virtues to defining
programs in terms of immutable data, but it's sometimes challenging to
do so. Unlike Haskell, which is considered a "pure" functional language
that strictly forbids such "side-effects" and "mutable state," Scala
doesn't force you to use immutable data. When you feel the need to be
able to reassign the value in a field or local variable (or function /
method parameter), you can use a "var" instead of a val.
