If you go to design view of your switchboard, you will see some buttons. They correspond to how many buttons you made from top down. Click on a button, bring up it's property sheet. On the OnCLick event something like =HandleButtonClick(,,) appears. This is a function the switchboard manager created and uses. You can click on this box and you'll see a drop down arrow. Click on the dropdown arrow and select Event Procedure. Then click on the Build Button (...). This will take you to VBA where you can write a procedure. Now when you click on this button, it will run your procedure, not the switchboard's managers.
