This isn't really a developer support questions. But anyway, to help you we'd have to know what you entered in all of the fields of the formula spline.

You cannot use "a" in this way in your formula, since C4D won't remember what "a" was when you set the formula. Instead convert the number to a string and embed it explicitly in the formula.
