Hello @shayshay1 and welcome to our friendly King Community. Are you requesting a life by clicking on the Heart that is to the left of your icon on the screen with the map on it? Once you click on the heart it gives you the option of sending the request to all your friends or only to ones that you specifically check. Are you saying that once you do this you get an additional message that says 'body required'? Usually when you get that message that means it wants you to write something in the 'body' of the message. However when I click on the heart and then click on the 'ask friends' next to the blue and white Facebook Icon, when I select a friend it opens a message but I don't have to type anything else - I just hit send. It sends an automated message requesting lives and won't let me type anything in the message.
Can you please provide a bit more information in the comment below and I will try and help you with your problem.
