Re: why doesn't $books[$val][display] show the value

It has to do with precedence (I think). When inside a double quoted string PHP evalutes "$books[$val]" *first* and doesn't catch that there's more to it... You can do this: $html.= " Yaddda yadda " . $books[$val][display]; And I think this (or something close to it): $html.= " Yaddda yadda {$books[$val][display]}"; On Thu, 9 May 2002, Peter J.
