title: Ms Access Combo Box option "All"
body: <p>I have a report, which is based on a query - 
  This query is filtered based on a combo box displaying all of my 'Clients'</p>
  
  <p>How could I include an option in this combo box  - which will remove the filter and show records for ALL of the clients?
  Eg, the user can either select 1 client at a time for the report, or they can select the ALL option which will display records for ALL the clients</p>
  
  <p>thank you</p>
