RadioButtonList value in repeater

[IFIA]

Hi,

I have a radiobuttonlist within a nested repeater, resulting in multiple radiobuttonlists.

On a button click how do I find out what those selected values of the radiobuttons were?

Code so far:

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (RepeaterItem rtpItem in RepWorkArea.Items)
        {
            Repeater rp = (Repeater)(rtpItem.FindControl("RepQuestions"));
            foreach (RepeaterItem rtpItem2 in rp.Items)
            {
                RadioButtonList rbl = (RadioButtonList)rtpItem2.FindControl("rblAnswers");
                label22.Text += rbl.SelectedItem.Value;
            }
        }
    }
