ik zie niet direct het probleem. Maar wanneer je hem werkend krijgt nadat je met javascript een refresh geeft, is het dan geen idee om deze refresh functie te starten wanneer de pagina wordt geladen?
 
dat zou ook kkunnen maar dat is niet goed. hijzou moeten werken zonder die refresh... en dat deed ie gister avond ook nog.. weetniet wat er nou mis was:P maar alsnog bedankt...
 
wat ik uit je javascript lees, moet je random getal tussen de 0 en 1000 liggen,
probeer eens <?php echo rand(0, 1000); ?>

ik zie alleen in je validatie script geen $_GET['rand'] staan. Heb je in dat script soms een regel verwijderd!
