Problem with PHP and PostgreSQL

I am having trouble with the following loops and such and accessing PostgreSQL 
database.
The errors i get are:

Warning: pg_num_fields(): supplied argument is not a valid PostgreSQL result 
resource in /var/www/html/PMS/csv_export.php on line 108

Warning: pg_fetch_row(): supplied argument is not a valid PostgreSQL result 
resource in /var/www/html/PMS/csv_export.php on line 118

Here is my Code Below:
//**** SQL Query
$query_panels = sprintf("SELECT * FROM %s WHERE utctime AT TIME ZONE 'MST' 
BETWEEN '%s' AND '%s' ORDER BY utctime %s", 
$MM_param1__panels,$MM_param2__panels,$MM_param3__panels,$MM_param4__panels);
//**** Count Fields 
$fieldcounts = pg_num_fields($query_panels); 
//**** List fields as first Row 
for($i = 0; $i < $fieldcounts; $i++)
 { 
        $fieldtype = pg_fieldtype($query_panels, $i); 
        echo "$fieldtype->name"; 
        if ($i < ($fieldcounts-1)) 
        echo ","; else echo "\n"; 
 } 
//**** Output each row of Data 
while ($myrow = pg_fetch_row($query_panels)) 
        { 
                for($i = 0; $i < $fieldcounts; $i++) 
                { 
                        $fieldname = pg_fieldname($query_panels, $i); 
                        if ($i < ($fieldcounts-1)) echo $myrow[$fieldname] . ", 
"; 
                        else echo $myrow[$fieldname] . "\n"; 
                } 
        }

Why do i get those errors?
Why is it not a valid result resource?
any help would be awsome.
Thanks,
