Pas aub ook je topic-titel aan, zodat duidelijk is waar het over gaat; menigeen die op phphulp een topic opent, doet dit omdat hij/zij een vraag heeft ;-)
Als iedereen dan als omschrijving zou meegeven php vraagje wordt het er niet duidelijker/overzichtelijker op.

Wat wil je bereiken?
Wat wil je doen?
Waarom pas je dat daar aan?
Waar moet ik het dan aan passen
Hoe roep je het script aan?
via de av.php
En hoe?
