'For' loop control variable cannot be of type '<type>'
You have attempted to use a loop control variable that is not a valid type. At the beginning of a For loop, the start point, the end point, and the step value are evaluated in textual order. All three expressions must be implicitly convertible to the type of the variable. If the For loop variable is of type Object, then at least one of the expressions at run time must be of a numeric type, and all three expressions must be coercible to the widest numeric type among them.
