In your first combo box you need to add the word DISTINCT for your row source of this control so that only 1 display is shown for each value of the Area currently you have many 1s and 2s displayed the row source should be
SELECT distinct TblName.Area FROM TblName ORDER BY TblName.Area;
For your second combo box you need to reference the control of cmb1 e.g. forms!form1!cmb1. The following code will concatenate the first last name into one field and only display the records that have the selected Area.
SELECT [CLName] & " " & [cfname] AS emp_name FROM TblName WHERE (((TblName.Area)=[forms]![form1]![cmb1])) ORDER BY [CLName] & " " & [cfname];
You will need to make changes to the layout as required.
Various contributors have sites that have examples of cascading combo boxes.
If have attached an updated version of your example using the above code.
