You can't put a calculation type expression in the specify find requests dialog. You either perform that calculation in a set variable step so that yo only refer to the variable, or you use a different approach for scripted finds:
Enter Find mode  ---> clear the pause check box
Set Field [Tasks::DropDeadDate ; "<" & Get ( CurrentDate ) + $Interval ]
Set Error Capture [on]
For other examples of criteria that can be set by the set field step, see the sample script near the beginning of this thread: http://forums.filemaker.com/posts/ba7347f58a
