Dear all,
sorry if I bother you with a silly pw input. I can't figure out why  
this input is wrong. Comparing with similar ones everything seems to  
be fine.
(I don't know if it is another clue but it can be open with no problem  
with PWgui).
Thanks in advanced for any helps you can give me.

where is the error in this input file?
