Fill down

Fill Down

I have a series of text that I need to copy down up to the netx. I need a macro, function or formula to be able to do this without doing it manually.

Here is an example:

Before
005
blank
blank
006
blank
blank
007
blank

After
005
005
005
006
006
006
007
007

Can you please help? I can change the values on the blank cells to anything I want.

Thanks!!
