Data copies on DropDownList change

Question

I'm using a DropDownList to pull up data from FormViews and properly calculate it. I use Label13 to see what the students Run Time is . If I select user one and place all the data it calculates a result, then I select a user two(which has no data yet), now if I select user one again without placing any information into user two it will copy Label13 results from user ones data to user two.(if that makes sense). Specifically Label13 .

Here is some code:

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        Label13.Text = "";

        if (DropDownList1.SelectedValue != "0")
        {
            Score();

        }
    }
 protected void Score()
    {
        Label13.Text = "";

        //Button1.Visible = true;
        Button5.Visible = true;
        Label19.Visible = false;
        UpdatePanel4.Visible = true;

        FormView2.DataBind();
        Label sitL = ((Label)FormView2.FindControl("SitUpsLabel"));
        Label pushL = ((Label)FormView2.FindControl("pushUpsLabel"));
        Label MeterL = ((Label)FormView2.FindControl("MeterLabel"));

        if (DropDownList1.SelectedValue != "0")
        {
            if (sitL.Text != "" || pushL.Text != "" || MeterL.Text != "")
            {

                int count = 0;
                int counter2 = 0;
                string test = sitL.Text;
                decimal val;
                string test2 = pushL.Text;
                decimal val2;
                string test3 = MeterL.Text;
                decimal val3;

                Decimal.TryParse(test, out val);
                Decimal.TryParse(test2, out val2);
                Decimal.TryParse(test3, out val3);
                //decimal holder = 0;
                //decimal holder2 = 0;
                //decimal scores = 0;


                for (int i = 0; i < situps.Length; i++)
                {
                    if (val == 30 + count)
                    {
                        Label14.Text = "SitUps Score: " + situps[i];
                        holder = situps[i];
                    }
                    count = count + 1;
                }
                for (int i = 0; i < pushups.Length; i++)
                {
                    if (val2 == 21 + counter2)

Answer 1

Check your page load isn't getting called twice

Put the code you use to populate your drop down in

    if  (!IsPostBack)
{
}

Answer 2

I messed around with some code in the DropDownList1_SelectedIndexChange method and also changed my FormView1 EnableViewState="False"

Here's the code for DropDownList1_SelectedIndexChange :

 protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
 {
     if (DropDownList1.SelectedValue != "0")
     {
         FormView2.DataBind();
         Label12.Text = "";
         Label13.Text = "";

         Button2_Click(sender, e);
         Button5.Visible = true;
         Label19.Visible = false;
         UpdatePanel4.Visible = true;
     }
     else
     {
         UpdatePanel4.Visible = false;
         Button5.Visible = false;
         Label19.Visible = true;
     }
 }
