[quote]    $query = "SELECT * FROM test WHERE id LIKE \"%$trimm%\" OR test1 LIKE  \"%$trimm%\" OR test2 LIKE \"%$trimm%\" ORDER BY id  DESC" ;
    // Execute the query to  get number of rows that contain search kewords
    $numresults=mysql_query ($query);
    $row_num_links_main =mysql_num_rows ($numresults);[/quote]

what am i doing wrong here? any help is welcome >_<

edit: i can paste the whole part if thats needed. just thought that since this is the part where it goes wrong , i could better just post that instead.
