What you have should work fine, assuming your date ($t) is in the correct format.

_NowCalcDate() would also likely be more appropriate than _NowCalc()

#include <Date.au3>

$t = "2010/08/11"
$diff = _DateDiff('D', $t, _NowCalcDate())
MsgBox(0,"", $diff)

If _DateDiff('D', $t, _NowCalcDate()) < 30 Then Beep(800,100)

Stick a "Msgbox(0,"",$t)" in there. What does it display?

I'm guessing it's not a valid date in the format of YYYY/MM/DD.

Edit: I might suggest dropping the "1" parameter from the FileGetTime() call and then add the following line:

$t = $t[0] & "\" & $t[1] & "\" & $t[2]

Test what comes out of that with a temporary Msgbox() statement.

FileGetTime returns a string in the format of YYYYMMDDHHMMSS, whereas _DateDiff is looking for a string in the format of "YYYY/MM/DD[ HH:MM:SS]" for the start and end dates, as you can see, they are not in the same format, so it will never work using those two functions together as is. You will need to reformat your FileGetTime returned result to match the format that _DateDiff requires. You could use a StringMid on $t and split them into the yyyy mm dd hh mm ss components, and then concantenate a string with those values $String = $YYYY & "/" & $mm & "/" & $dd ...
