just confused, because tried to do index +1, but it just goes crazy. When I do the ++ everything is fine

5,487 PointsThe statement, index + 1, doesn't assign to anything. You probably mean
index = index + 1
This is assigning the value of the variable index to index + 1.
index++ is shorthand for index = index + 1
