hi,

a user selects which chapter to answer questions on (in dropdown menu), this result is caught in $chap.

 

i want a the count function in a query, to use this variable to change the query depending upon what chapter is chosen. I have tried and tested the query is fine. i just dont know how to write this bit...

 

$query = "SELECT ChapterID, COUNT( ******) FROM question GROUP BY ChapterID"; 
// query from total questions in chapter - amount of questions with true & false workout question number! 	 
$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){
echo "There are ". $row['COUNT(*****)']." questions in this chapter";
echo "<br />";
}

is it COUNT('$chap') or COUNT($chap) or COUNT(ChapterID = '$chap') etc etc?

thanks
