Is it possible to attach a script to a screen query button that will perform the sort of search: Find >= (today's date - 30 days) in the accession date field and return a list of results.
I am interested in perhaps having a feature that would enable users of a textbase to then run sch a script which might automatically email them the results.

The following script button will perform the search (assuming you name your script button "button" and the query box for the date field "boxDate").

function button_onClick()
{
Form.boxes("boxDate").content = "@DATE - 30";
Command.executeQuery();
}

You could then have another script button that would send the e-mail using Command.sendMailEx(SendMailDescriptor) as described in the "Command Object" topic in the DB/TextWorks Help.
