title: Difference between the "On Open" event and the "On Load" event for a data-entry Form
body: <p>I have designed a data-entry Form for conducting a survey.
  For each survey question, only one answer can be selected from a list of multiple-choice answers.
  I have used an "Option group"(a set of radio buttons)Control for each set of multiple-choice answers such that each possible answer within the set has a radio button beside it which when clicked, would select that answer. 
  Whenever the form is initially displayed(I'm not sure whether to say "opened" or "loaded") for use, I want each "Option group" to have none of its answers selected.
  I know the VBA code to use to achieve this. I wish to know the difference between the "On Load" event and the "On Open" event for any data-entry Form.
  After knowing the difference, I will know and understand which of these two events to apply the VBA code to.</p>
