I am sure I am just overlooking something simple but I can't figure it out. Here is the code:

//Member functions for bank class

#include "updater.h"

updater::updater()
{
	day = 0;
}

updater::~updater()
{


}

int nextDay(execNextDay order)
{
	cout << "\n\nDay " << day << endl << endl;
	day=day+order.numDays;

}

returnFinAssets finAssets()
{
	returnFinAssets reply;
	reply.amtGold = mkt.amtGold;
	reply.amtSilv = mkt.amtSilv;
	reply.amtPlat = mkt.amtPlat;
	reply.money = mkt.money;
	return returnFinAssets;
}


Here's the errors:

updater.cpp: In function ‘int nextDay(execNextDay)’:
updater.cpp:18: error: ‘day’ was not declared in this scope
updater.cpp: In function ‘returnFinAssets finAssets()’:
updater.cpp:26: error: ‘mkt’ was not declared in this scope
updater.cpp:30: error: expected primary-expression before ‘;’ token


Thanks

You forgot updater:: in front of your method names.
WilliamERoberts (10)
Yes I did. Thanks.

Also just noticed the other error. It's all good now.
