Jonathan asks:

$query = "SELECT * FROM $table WHERE CustNo='$CustNo'";

Pretty vanilla stuff.

[ . . . ]

> BUT! If the field is NULL, php spits out this:

> f:\website\pmaco\admin\contacts1.php on line 241"

The offending line was:

if ($row["Website"]) {
    // do stuff
   }

and is now:

if (!is_null($row["Website"])) {
     if (strlen($row["Website"])) {
    // do stuff
   }
}

Same warning msg. But if I substitute a numberic index, as in:

if ($row[33]) {
    // do stuff
   }

it works fine. But I need to use the associative index.
