Have you dragged the proper input GO in the Plan Name Input field in the inspector?

Yeah i have

Do you have a Text component on any of its children?
Could you Debug Log out both the planNameInput and the planNameInput.GetComponentInChildren() right before the 123rd line? So we can see what is null?
