Problem with scope of variables

[JustBobC]

In the following code the compiler says that the variable "currentRow" is unused in "on_pushButton_2_clicked()" and not declared in "on_pushButton_clicked()". I've tried declaring "int currentRow" in every place and in every way I can think of and nothing works. Seems like a trivial issue, but I'm stumped.

void Dialog::on_pushButton_2_clicked()
{
// declare and set variables
    QMessageBox::information(this, "Settings","Setting Row and Column");
    int currentRow = 3;
    int currentCol = 5;
}
 
void Dialog::on_pushButton_clicked()
{
//  view variable values
    QString nmbr = QString::number(currentRow);
    QMessageBox::information(this,"info","currentRow = " + nmbr);
}

void Dialog::on_pushButton_2_clicked()
{
// declare and set variables
    QMessageBox::information(this, "Settings","Setting Row and Column");
    int currentRow = 3;
    int currentCol = 5;
}

void Dialog::on_pushButton_clicked()
{
//  view variable values
    QString nmbr = QString::number(currentRow);
    QMessageBox::information(this,"info","currentRow = " + nmbr);
}
