I'm guessing that Timer1.Interval takes a Double, but it can't convert the contents of TextBox3.Text to that type. As a test, try putting a number in the line you assign a value for Timer1.Interval. If it doesn't give you the error, you must find out why it can't convert the text to a double (probably you don't have a number in the text?).
