title: MS Access form -> Combox used to filter other combobox results
body: <p>I have a dropdown combo box in a form for a <code>"Project_ID"</code> called: <code>Combo28</code> (this is the primary key basically). There are also 5 other <code>"Error_Code"</code> combo boxes called: <code>cboErrCod1, cboErrCod2, cboErrCod3, cboErrCod4, cboErrCod5.</code>  </p>
  
  <p>I'm looking to create some sort of "On Change" code that will only display the Error Codes pertaining to the Project_ID selected in the Combo box <code>"Combo28"</code> only.</p>
  
  <p>The error codes are stored in a separate table and each code is associate to a particular <code>project_Id.</code></p>
  
  <p>Can anyone help?</p>
