should be:
substr( rpad(‘*’,40*round( VALORE/max(VALORE)over(),2),’*'),1,40) PLOTTED_VALORE

Otherwise – very good post! Thanks

très bon , votre site web modèle est vraiment grand, je suis chasse pour un nouveau thème pour mon moncler doudoune propre site web , j’aime vôtre, maintenant Je vais à aller chercher le même design !…

Strangely the two guys from Flicker who preached on teamwork do not seem to be anyway comfortable with one another. Just watch the body language between the two, in particular at the opening when the guy on the right swung a very aggressive gesture to the left and how the guy on the left (british) ducked away. lol

It worked after the change u suggested.

Thanks,
Dev

$sth = $prodh->prepare( <<EOSQL );

have become:

$sth = $prodh->prepare( < <EOSQL );

there is an extra blank between < operators. try to remove it and let me know!
