Dear Francois,
As you say there were a couple of things wrong in your INP file:
1. The bond valence sum for W will get calculated for each W in the cell.
The valence sum then becomes 6*4=24 in this specific case.
2. You just need to specify the atom labels as O1 O3 and O4.

Dear Carmelo,
What website are you trying to access? I had to move all my pages to wordpress
at the end of last year. There was meant to be a redirect from the old pages,
but maybe that has failed.
You should be able to find the equivalent content via:
