You need to be clearer about what output you want and how and where you're using it. — rory.ap, Jan 19 '17 at 13:04
A string "100" is not an integer 100 (note the quotes). The plus operator works differently if it is applied to a string or to a number. Now try to apply this concept to your code. — Steve, Jan 19 '17 at 13:05
Instead of misusing the text you can store any value in the Tag of the RBs. — TaW, Jan 19 '17 at 13:05

First, you have to make sure that ChosenMovie is an int type.

If the number you want to add to ChosenMovie comes from a string like label2.Text that you wrote on a commented line, then you can use Convert.ToInt32() or int.TryParse():

...

if (radioButton1.Checked)
{
    //label2.Text = "100";

    // by Convert.ToInt32()
    ChosenMovie = ChosenMovie + Convert.ToInt32(label2.Text);

    // or, by int.TryParse()
    ChosenMovie = ChosenMovie + int.TryParse(label2.Text);
}
