Remove your IF and replace with IIF
Chances are your script would work better with iif anyway and be far
more flexible
If you absolutely must use IF then do it with a for loop through the
bars, and give your self a chance at flexibility to scan whatever day
you want
To give a proper repsonse to a question that has only given part
information (remember that what is posted is assumed to be the total
information), we need to see your entire code, otherwise we go through
many posts becasue of "Yes But"

I want to run a scan on a certain day (e.g., 3/4/2009) using that day's close data, so I set the Range in Automatic Analysis as "from 3/4/2009 to 3/4/2009", in the AFL script I used Last=LastValue(Close) to try to get the close price on 3/4/2009, but it actually returned today's close price.
