[PHP] sql looping problem??

[Wade Halsey]

Hi

I have the following code

/*number of times to run*/
$NumCases = $HTTP_POST_VARS['txtNumCases'];
/*execute the sql*/
$sqlLargeRequest = sqlexecute($LargeRequest);

for ($val = 0;  $val < $NumCases; ++$val){
 if ($val < $NumCases) {


$details = sqlFetchObject( $sqlLargeRequest );

$AccNo = $details ->ACCNO;
etc etc


It executes the correct number of times but doesnt move to the next record.Im using an 
Interbase DB.  Any ideas??

TIA
Wade
