function undeclared error

[Seraphimsan]

I'm compiling my first multilayer perceptron, and this error keeps coming up in compile.

30 C:\Dev-Cpp\main.cpp `inputcount' undeclared (first use this function)
34 C:\Dev-Cpp\main.cpp `input' undeclared (first use this function)

I can't figure out why though, I have a shadow copy of my CreateNetwork function in the main program, and it recognizes it, it has to cause it doesnt get hung up on the reference to that function.

well anyways, Here is the code, perceptron header first, neuralnet header second, and main cpp file last.
perceptron.h:
[code="perceptron.h"]
#include <iostream>
#include <cstdlib>
#include <math.h>

#ifndef _PERCEPTRON_H_
#define _PERCEPTRON_H_

double randgauss( double min, double max, double sigma, double centre)
{
double random = (min + (max-min) * (double)rand()/RAND_MAX); //create random domain between [min,max]

double tmp = (random-centre)/sigma;
double gauss= exp(-tmp*tmp/2); //gaussian formula

return gauss;

struct perceptron

      ConnectionNeuron[i] = toNeuron;
      ConnectionID[i] = toNeuron.ID;
}

Yea I know, Seriously needs cleaning up... But bare with me please?

You haven't actually declared a variable named inputcount anywhere. Line 19 is just a function declaration.

oh wow.....Once more I fail hard...lulz.

Well thanks jsmith.

edit: well that out of the way, I found out that I was calling the wrong header....
So that fixed, It still doesnt see input. But I think I can figure it out from here.
