Hello
I have found the following script php/java for dynamic menu lists. Where a
selection from the first updates (filters items in) the other. I have
modified it for my tables.
However I am getting an error
Parse error: parse error, unexpected T_VAR in
e:\domains\i\iddsoftware.co.uk\user\htdocs\QuestionDB\Questions.php on line
42
line 42 being
var mainselect = document.FormName.MainCategory;
Im fairly new to php and dont use Java upto now. Can anyone see where I ve
gone wrong

StatusID = 1 ORDER BY SubjectDesc ASC";
$Result = mysql_query( $Query, $conn );
