Hej,
Jeg har lige prøvet at kigge igennem koden og har fundet nogle små fejl.
Der var et åpar steder hvor du bruger :
if ($somevariable = 1)
do_something;
else
do_something_else;
Det som du gør ovenfor er at tildele variablen en værdi på 1 og der efter ser du på om den er true.
Der skulle stå:
if ($somevariable == 1) osv.
Der manglede også en initialisering af variablen $iCount.
Jeg kunne også se at variablen $start egentlig sendes som param til din php side, så der har jeg ændret koden til at hente $start via $_GET['start'].
Jeg har rettet lidt andre småting til i din koden (har dog ikke prøvet det) så nu håber jeg at det virker :0).
God fornøjelse
Michael.
