Welcome to IRV2! We're sure glad you joined the gang!
Sounds like you didn't have one end of the awning dropped to run the water off? You would probably want to get the model number of the awning and post specific questions in the General Discussion or RV Systems and Appliances areas of the forum!
Good luck, happy trails, and God bless!
