Template Function results in Identifier not found

I've created this template, and put it at the very top of my .cpp above main() but I am still getting the following

error: C3861: 'ConvertNumbertoString': identifier not found.

Here is the template:

template<class T>
string ConvertNumberstoString(T number)
{
    string outPut;
    stringstream convert;

    convert << number;
    outPut = convert.str();

    return outPut;
}

I know this is probably a stupid function to most of you guys, but it's what I need at the moment.

I can't figure out how to get rid of this error so that I can use it in my program.

Any thoughts?

You want to return a string from the function template:

// In your cpp:

template<class T>
string ConvertNumberstoString(const T &number)
{
    stringstream convert;
    convert << number;
    return convert.str();
}

int main()
{
    string s = ConvertNumberstoString(42);
}
