deletion of a file

hi
im using hazel to clear my downloads folder
i want it to move any files to trash that i have opened and no longer need (did not move them or hazel did not move them)
so i set up the following rule:

but it removes all files immediatly
is this because there is no last opened date when the file is made and therefore it just deletes it? If so, is there any other way to do it? i tried date created but got the same results
thanks
