Hi I have this LinkedHashMap

{0={Question=What is Gravity?, Answer=Whatever}, 1={Question=What is Motion?, Answer=Whatever}}

displayed by the following code=

linkedHashMapForLessonContent = (intent.getSerializableExtra(tags?.LESSON_MAP_TAG_NAME) as WrapperSerializer<LinkedHashMap<String, Any>>).get() as LinkedHashMap<String, Any>
Log.e("helloworld", linkedHashMapForLessonContent!!.toString())

until then it works perfectly, then I want to access the 0 value with the following code=

val d = linkedHashMapForLessonContent!!["0"] as LinkedHashMap<String, Any>

which gives me an error and I do not know why, what I want to get is the Question value, I've been stuck for hours in that same problem so if someone can help me I would be so thankful :)

Thank you and have a good coding :)
