I lost autofill
Use AutoComplete when entering formulas
Turn on AutoComplete
On the Excel menu, click Preferences.
Under Formulas and Lists, click AutoComplete.
Select the Show AutoComplete options for functions and named ranges check box.
Decide when you want the AutoComplete menu to appear
You can always show the AutoComplete menu when you begin typing a formula, or to narrow down the number of possible entries that you see, you can display the menu only after you've typed a certain number of letters.
On the Excel menu, click Preferences.
Under Formulas and Lists, click AutoComplete.
In the Show options after typing box, enter the number of letters that you want to type before the AutoComplete menu appears.
...you will find more informations in the upper link.
Hope I could help you with these information / links.
