Jill , I think you need to start over again ..take him out (don't put him out) and use a word or phrase so he associates it with the action (hurry up ! or go potty or whaever) praise him when he performs ..act as though he is a new pup again (not that he is very old at 11 weeks).
The main thing is to get him to associate peeing and pooing with going outside ...lots of praise when he performs out there
