AMBER: LES question

Hi:
    I posted this problem about two weeks ago. And I really appreciate
all the responses, which helped me solve several problems. But
sander.LES still can't be run correctly.
    Here is the output I got from sander.LES. 1). The number of water
molecule is wrong. It should be about 15000. 2). The total charge is a
little bit larger than what it should be. I think something is wrong
with topology file. But I exactly follow the manual. And there is no
complaint when I run addles.What could be wrong?

Thanks in advance.

Best,
Lishan
