[FX.php List] Error code question

[Jim McNeely]

I am having some trouble with a PHP file that was working perfectly with 
FMSA 7, but upon updating to FMSA 8 is not working properly. Other 
queries are working correctly that reference the same FM file, but not 
this one. I used var_dump() to examine the contents of the array that 
isn't working, and got this; what EXACTLY is the filemaker error in all 
of this? - Also, if I comment the web_web query and do the web_products 
query, it works. And yes, the layout is there and is named correctly, as 
are all of the fields. So, WHAT???!!!  TIA, Jim
==========================
query:
==========================
$linkq = new FX("10.42.6.153","80");   
//$linkq->SetDBData("soi_data.fp7", "web_products");
$linkq->SetDBData("soi_data.fp7", "web_web");

$linkq->SetDBUserPass("web","bewbew2005");

//$linkq->AddDBParam("f_new_prd_flag", "1");
$linkq->AddDBParam("c_table", "Links");

$link=$linkq->FMFind();

echo var_dump($link);

==========================
result:
==========================
