Find function not working in dialog form

I've created an employee award trackiing database.  In my main form it lists the awards and the employees who have been nominated.  I've got a command button which opens a dialog form I created to allow user to add or edit employee information.  I can use the navigation buttons to go from employee to employee, but with over 600 names I would rather search.  Here is my problem.  I can't search in any of the fields!  The dialog box's control source is my employee info table (tblEmployees).  Ideally, I want the user to be able to search for an employees name and be able to edit any of the information for that employee.  Ctrl + F does nothing.   Why??  Help!!
