Hello Access Family!

This is probably an easy question, however, I am relatively "clueless" in writing code. I've added a Calendar to my form. I want to be able to click on the day of the month and it automatically changes in my Control Source. Currently, I click on the date and then have to hit the enter key before it will change in the control source. Can someone walk me through this process...step by step...from inserting the calendar on the form to it actually working? I'll need to know where in the heck to place that darn code )

Thanks a bunch!
