Christian,

Thanks for the help! It no longer says that the query was empty, but now it's saying "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\Program Files\Apache Group\Apache2\test\movie_details.php on line 117"

Line 117 reads:
while($review_row = mysql_fetch_array($review_result))

The entire "while" is:
while($review_row = mysql_fetch_array($review_result))
{
     $review_flag =1;
     $review_title[] = $review_row['review_name'];
     $reviewer_name[] = ucwords($review_row['review_reviewer_name']);
     $review[] = $review_row['review_comment'];
     $review_date[] = $review_row['review_date'];
     $review_rating[] = generate_ratings($review_row['review_rating']);
}

Any further help is appreciated!
