c++ getline() error, no instance of overload function "getline" matches the argument list

I am getting the following error when using a getline() function:

no instance of overload function "getline" matches the argument list

In one class named "Time" I use it when reading in the following input:

istream & operator >> (istream & input, Time & C) /// An input stream for the hour     minutes and seconds
{
char ch;
input >> C.hour >> ch >> C.minute >> ch >> C.second;
getline(input,C.ampm,',');

return input;   /// Returning the input value
}

This works fine, but I also want to use it for another class called "Shares":

istream & operator >> (istream & input, Shares & C) /// An input stream for the day, month and year
{
char ch;
input >> C.price >> ch >> C.volume >> ch >> C.value >> ch;
getline(input,C.value,',');

return input;   /// Returning the input value
}

However, the getline function in the "shares" class is giving me the error. Both classes are using the libraries:

#include <iostream>
#include <string>

How can I overcome this? Thanks

getline(input,C.value,',');

based on the comments, you wrote that C.value is double. That will not fly because as others pointed out, the expected parameter is a string type in there.

You would need to read into a temporary string and then convert it to your double. The latter step is simple, but even simpler with C++11's std::stod.

Therefore, you would be writing something like this:

std::string valueString;
getline(input, valueString, ',');
C.value = std::stod(valueString);
