QMessageBox error

Hi. I've got a problem. I have a piece of code:

Code:

---

int ret = QMessageBox::Information(this, tr("Speed Units Converter"),
                   tr("You can't convert value to the same unit"),
                   QMessageBox::Ok | QMessageBox::Default);
                   if (ret == QMessageBox::Ok)
                   {
                   return false;
                   }

---

And I reach error that Information cannot be used as a function :eek:
Regards

QMessageBox::information() with lower case i.

Thanks, now's all right. But there's another problem. Here's piece of code

Code:

---

if (beaufortBox->isChecked() && knotBox_2->isChecked())
          {
                               convertDialog->setWindowTitle("Converting value from Beaufort to Knot");// this is error line
                               toLabel->setText("Knot(s)");
                               displayConvertDialog();                             
          }

---

And I've got error, that expected primary expression before -> token. What is this problem about? Regards

Where is "convertDialog" declared?

it is form created by designer, I was subclassing this form.
