Help Stuck on meeting up with Mr.BlackLock on Saddle up with Pippa Funnell. Ive talked to everyone i can find at the farm and in town and i have the paper from the phone book

Once you get to Mr Blacklock's house, view (through your inventory) the paper you tore from the phone book. It will have a 6 digit phone number for his company/house. Type this into the keypad.
