I'm afraid that "aq_parent.title" also throws "Missing input variable".

When you say "real expression", I take it you mean I need to construct 
something which grabs the parent's title and refer to that in the 
sqlvar? Could that be something which could live in the root, and be 
inherited? We've now got tho the point where in our zillions of parallel 
sub-folders, the only repeated object is the "index_html" python script 
(which you originally helped us with!), and if at all possible I'd like 
to avoid duplicating anything else!

It's taken some time, but it all feels a lot better "lubricated" bow! <g>
