[SOLVED]Help - Unclear errors - Don't know where to post.

Hi, first off all I'm sorry if I posted this in the incorrect section, the forums are kinda unclear for me. Also, I'm new to QT since a few days, I know basic C++ and I tried to make a payday calculator, I'm stuck with some code. The errors seem unclear for me, thanks in advance and again I'm sorry if I posted this incorrectly. Also, the script itself isn't made to work yet like it should, I just needed to do some testing first.

mainwindow.cpp
@#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent):QMainWindow(parent),ui(new Ui::MainWindow){

ui->setupUi(this);
ui->mainTable->setColumnWidth(0,50);
ui->mainTable->setColumnWidth(1,151);

ui->mainTable->verticalHeader()->setVisible(false);

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::addTaxes(int time, int taxes, int net){
int x = 0;
int rate = 2;

ui->mainTable->setRowCount(time);

for(int i=0; i<time; i++){
    QTableWidgetItem* item = new QTableWidgetItem();
    QTableWidgetItem* itemDeux = new QTableWidgetItem();

    x = ((net/100)*rate)-taxes;
    net = net + x;
    item->setText(QString::number(i));
    ui->mainTable->setItem(i,0,item);

    itemDeux->setText("$" + QString::number(net));
    ui->mainTable->setItem(i,1,itemDeux);

    ui->mainTable->setRowHeight(i,10);
}

}

void MainWindow::on_calculateButton_clicked(){
//int time = ui->timeEdit->text().toInt();
int taxes = 0;
int net = 0;
int time = 0;

addTaxes(time,taxes,net);

}

Hi, and welcome to the Qt Dev Net!

What you say in your .h file needs to match what you say in your .cpp file:

[quote]
@
// mainwindow.h
void addTaxes();
@

@
// mainwindow.cpp
void MainWindow::addTaxes(int time, int taxes, int net){
...
@
[/quote]Your .h file says addTaxes takes 0 parameters, but your .cpp file says it takes 3 int parameters. Which is is correct?

Thanks a lot, I knew about this but I forgot to add the parameters to the header file as you said.
