What causes "Undefined Index" Errors?

HELP! This MySQLi recordset:

35. <?php
36. $rsSearch = new WA_MySQLi_RS("rsSearch",$icmids,0);
37. $rsSearch->setQuery("SELECT * FROM abstracts WHERE Author = %s OR FileName LIKE %s");
38. $rsSearch->bindParam("text", "".$_GET['Author'] ."", "-1xyz"); //varAuthor
39. $rsSearch->bindParam("text", "".$_GET['FileName'] ."", "-1xyz"); //varFileName
40. $rsSearch->execute();

is giving these errors:

Notice: Undefined index: Author in /Library/WebServer/Documents/ICMIDS/admin_abstracts_edit.php on line 38
Notice: Undefined index: FileName in /Library/WebServer/Documents/ICMIDS/admin_abstracts_edit.php on line 39
Error in SQL syntax

Anyone know what is causing this and how to fix?
