What is wrong here?

I am working on a simple text adventure game. I have implemented one
word commands and a bit for two words. I have a problem though the
movement commands n and s (north and south respectivly) don't work. I
can't figure out why!

struct command_v
{
string name;
bool (*vfunc)();
bool (*dfunc)();
};

bool (*dfunc)(vector <string> input);
};

What exactly does "don't work" mean?
Don't they compile? What did the compiler say?
Are they doing something unexpected? What?
Are they crashing? Where?
I can't figure out why!

Reduce your code to the minimum possible, but complete program that
shows the error. It often happens that, while reducing the code, you
find the error yourself. If not, post the result again. Your current
program is too long, so probably nobody will bother reading through it.
