Performing Math Calculations on TextBox Contents

I have a couple of text boxes on a form that I want to take the contents, perform one mathematical calculation against it and set the contents of a label with the results. I'd like to have the label set upon exit of the text box field. The textbox name is txtOpBudgAmt and the drop down is ddlTime1.

I have attached my code in the OnTextChanged event for the textbox txtOpBudgAmt which isn't working. What am I doing wrong here?

if (ddlTime1.SelectedValue == "Week")
        {
            int intWeeklyAmt Convert Int32(txtOpBudgAmt) * 52;
            lblOpBudgCalcAmt = intWeeklyAmt.ToString();
        }

are you sure this is the code and you are not missing anything
because by just having a look at your code i can see that the code should not compile
modify your code as i have shown below

if (ddlTime1.SelectedValue == "Week")
{
            int intWeeklyAmt = Convert Int32(txtOpBudgAmt.Text) * 52;
            lblOpBudgCalcAmt.Text = intWeeklyAmt.ToString();
}

Okay - i modified your's slightly to the attached which works now. It refreshes the whole page which works, but is slightly annoying. So, I'm going to accept your solution and then try to figure out how to update the label without refreshing the entire page. Maybe an updatepanel...


     double dWeeklyAmt = Convert.ToDouble(txtOpBudgAmt.Text) * 52;
     lblOpBudgCalcAmt.Text = dWeeklyAmt.ToString();
