IIF together with range selection solves my problem. Lastvalue doesn't work because of the reason Graham mentioned.
Thanks for everyone's reply.

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.
