Bind_param error without object with mysqli

Question

When I try to insert the start line of a table that will track daily views, I get an error:

Fatal error : call of bind_param () member function for non-object in /.../functions.php on line 157 strong>

This line is the last of the following groups:

if($stats_found) {
 $sqlquery = "UPDATE vid_stats SET views = ? WHERE title = ? AND format = ? AND date = ? AND results = ?";
 $views++;
} else {
 $sqlquery = "INSERT INTO vid_stats (views, title, format, results) values (?, ?, ?, ? )";
 $views = 1;
}

$stmt = $mysqli->prepare($sqlquery);
/* bind parameters for markers */
$stmt->bind_param("dsss", $views, $title, $format, "success");

Any hints of a problem?

Just in case, this is a problem with the surrounding code, here is the full function:

function updateViewCount($title, $format, $results) {
 //update view count
 global $mysqli;
 $views = 0;
 if ($stmt = $mysqli->prepare("SELECT views FROM vid_stats WHERE title = ? AND format = ? AND date = ?")) {

  /* bind parameters for markers */
  $stmt->bind_param("ssd", $title, $format, date("Y-m-d"));

  /* execute query */
  $stmt->execute();

  /* bind result variables */
  $stmt->bind_result($views);

  /* fetch value */
  if ($stmt->fetch()) {
   $stats_found = true;
  } else { $stats_found = false; }

  /* close statement */
  $stmt->close();

  if($stats_found) {
   $sqlquery = "UPDATE vid_stats SET views = ? WHERE title = ? AND format = ? AND date = ? AND results = ?";
   $views++;
  } else {
   $sqlquery = "INSERT INTO vid_stats (views, title, format, results) values (?, ?, ?, ? )";
   $views = 1;
  }

  $stmt = $mysqli->prepare($sqlquery);
  /* bind parameters for markers */
  echo $sqlquery."<br>".$views."<br>".$title."<br>".$format;
  $stmt->bind_param("dsss", $views, $title, $format, "success");

  /* execute query */
  $stmt->execute();

  /* close statement */
  $stmt->close();
 }
}

The problem was a user error: I incorrectly named the column result.

, echo $mysqli->error; $stmt = $mysqli->prepare($sqlquery);, .
