what happens if you do this? $result = mysql_query("SELECT MAX(Thought_Num) as Thought_Num FROM quotes",$db); I'm thinking that the column name in your original query is being called "MAX(Thought_Num)" and not "Thought_Num".

I'll try to be respectful of your time and patience, and apoligize in advance for my "greeness" - I am 2 weeks into PHP/MySQL. I am trying to select the higest value from the column Thought_Num below. But it returns nothing. <?PHP $db = mysql_connect("localhost", "root"); mysql_select_db("DynaSite",$db); $result = mysql_query("SELECT MAX(Thought_Num) FROM quotes",$db); $myrow = mysql_fetch_array($result); print "the result is $myrow[Thought_Num]"; ?> If I change my select to something that without the MAX (e.g. Select from quotes where DocID=1), the code works fine.
