Payload not moving after first CP

I was making my first Payload map so i naturally looked towards the guide on the source sdk wiki. Sure, everything works well until i capture the first Control point. Then, where the spot where it shows my payload is moving, it shows a blocked sign. My payload doesn't move anymore after that even though there are 2 control points. D: help plz :O

Bit late, lol, i deleted my whole payload map and switched it to cp but thanks for the replies.
And i did change the Trigger_capture_areas control point associated with it, but nothing happened. CAn't be bothered now
