How to get the selected value of a UIPickerview fr

Question

In my view I have 2 TextFields, 1 Label, 1 Picker and 1 button

I want to the label to have the value of the 2 textfields and the selected value of the picker when the button is clicked.

The following is my button click code

-(IBAction)changeTheTextOfTheLabel
{
    NSInteger row;
    row = [listPicker selectedRowInComponent:0];
    NSString *fullName = [[NSString alloc] initWithFormat:@"%@ %@ (%@)",firstNameTextView.text,lastNameTextView.text, [listArray objectAtIndex:row]];
    [fullNameLabel setText:fullName];
    [fullName release];
}

The above code work fine except that it always put the first item ofthe picker in the label no matter which row it was selected.

Thank you.

It doesn't look like the instance variable listPicker is connected to the UIPickerView in IB.

row = [listPicker selectedRowInComponent:0];

Here row will always be zero if listPicker is nil and that should happen only when listPicker is not connected.
