On line 2, you're missing a semi-colon at the end.
on line 4, 6 and 8 you are using
=== instead of
= to assign a variable a new value. We use
=== when comparing a string and it's strict, so they have to be of the same type.
The strict equality operator === only considers values equal that have the same type. The “normal” (or lenient) equality operator == tries to convert values of different types, before comparing like strict equality. For more information, take a quick read here.
On line 5, go with
else if, you're capitalizing the 'E'.
On line 7 you are giving it a condition, but it's an else statement, there can be no condition. Use an
else if if you require another condition.
Let me know if that works.
