Undefined reference, C++?

When attempting to compile my program, I get an error of "undefined reference to search (char, int, int, int)'. Below is a portion of the program I am writing for my project, so any input on what I may have done wrong would be greatly appreciated. This seems to be my only issue right now with it, and it's anything like my last question it's an obvious mistake I'm missing.

#include <iostream> // cin/cout

#include <fstream> // stream

#include <iomanip> // setw

using namespace std;

void search (char, int, int, int);

int main ()

{

int i = 0;

int SIZE = 0;

char numbers[50];

int tally[50];

int source, num;

char file_name[16];

do

{

cout << "Enter 1 for manual input from keyboard, 2 for reading from a file: ";

cin >> source;

} while (!((source == 1) || (source == 2)));

if (source == 1) // keyboard

{

do

{

cout << "Enter a number (99999 to end): ";

cin >> num;

search (numbers[i], tally[i], num, SIZE);

} while (num != 99999);

}

}

void search (char numbers[], int tally[], int target, int SIZE)

{

int index = 0;

bool found = false;

while ((!found) && (index < SIZE))

{

if (target == numbers[index])

found = true;

else

index++;

}

if (found)

{

tally[index]++;

}

else

{

numbers[SIZE] = target;

tally[SIZE] = 1;

SIZE++;

}

return;

}
