Fable II - Stuck in Love hurts Quest, Help?

I'm at the part "Retrive part of the body from a tomb in WraithMarsh". So I'm already inside the tomb. But there is one location where a farting statue needs to be activated to open a door. So I did a fart action and the door on the right opened. However once you get into the door to the next room you need to stand up on a activation stone and when you see from there , you see a target upstairs straight ahead but far away, and I tried aiming with my gun very closely and shooting it, but it looks like it won't accept it and it's too far away.

BTW, there is a gate in the previous room which is left of the statue, and it won't open (only the fate on the righ t of the statue oepns). So I'm thinking if you get into the left gate, I can get upstairs someone in the next room. What should I do to activate this gate or hit that distant target?
