Get rid of the blanks in the list. To create a drop-down menu for a cell where the source list will vary in length select the cell and then choose the menu command Data->Validation to open the Data Validation dialog box. Choose List from the Allow drop-down list. In the Source text box enter the following formula:
=OFFSET(A1,0,0,SUMPRODUCT((A1:A100<>"")*1),1)
where A1 is the first cell in the list of values and A1:A100 is the array of cells representing the largest possible list. If the range of drop-down list values has been named then use this formula:
=OFFSET(DropdownValues,0,0,SUMPRODUCT((DropdownValues<>"")*1),1)
Note that SUMPRODUCT is used instead of COUNTA because COUNTA counts cells with formulas even though the formula result is empty.
