I don't understand what you mean by "get the map one time only"... Steve

That works, but is there a way to get the map one time only?

You'd do something like:

  ...&mode=itemnquery&qlayer=schools&qitem=id&qstring=/id1|id2|id3/&...

Hello all.

I have a layer of school district polygons that I am trying to query. I can successfully do an itemquery on a single value and get a map with the chosen district highlighted.
What I'm stumped on is how to query for multiple districts... I saw the documentation for "Mapserver expressions", but I don't see how to use them to do this. I tried embedding an OR expression into the qstring, but mapserver wouldn't take it. From what I gather, qstring must be a regular expression.

Thanks in advance for your help.
