Bertie's first yucky day.

We woke up to 40 degree weather and rain.  I opened the back door for Bertram's morning potty and he stopped mid step and back peddled into me.  I decided to carry him out after grabbing an umbrella from the garage.  He peed all down my side.  I ended up chasing after him outside holding the umbrella over him.  He got damp, I was dripping wet.  He remains confined to quarters and only coming out to go outside.  He doesn't seem to be learning.  I am overwhelmed with guilt.  I am at a loss as to what else to do.   Any tips on this potty training stuff would be greatly appreciated.
