mysql_query problem with multi dim arrays

hi... i cant cut and paste my exact mysql query because it takes the '' stuff out doubles the $'s and the ,'s in the whole thing (dont know why but anyways...)... i have a query that goes something like this: mysql_query("insert into $GuestbookTable values(NULL, '$_SESSION[add][date]', '$_SESSION[add][name]', $_SESSION[add][email].........."); the problem i get is using the multi dimentional arrays to insert text and stuff all i actually get when i echo the query or do a real insert is: echoed it would be something like: insert into rnjresort.guestbook values(NULL, 'array([add]), 'array([add])', 'array([add])', ....... any idea what the problem is here? do i have the '' in the wrong places?? i know that works on single dimention arrays but doubled?
