Compare files with creationdate

Hi, I'm a total NEW user of AutoIt. I used to use WinBatch but now I have some troubles with it. Moreover I think AutoIt is a better tool.

I allready tried the first step in this NEW medium for me.

I want to compare a file with the current date.

If there's no differance in the DAY there's no action wanted. If there is a time (creation) different action is needed.
I tried the TimeDiff and the FileTimeGet

I tried: (I did it like this in WinBatch and thought these programs are quite similar.)

  now=TimeYmdHms()
  a = FileYmdHms("d:\AccessdB.mdb")
  Action=TimeDiffDays(now, a)
  if Action==0

;then I know what action should follow

But this want work ....  Is there someone who can help?
