I have a text field in a webform which I would like to validate against a
SQL table. When the user inputs an incorrect value I would like the custom
validator to trigger a new window(browser) giving a list or some other
selection. When the window is closed it then returns the selected value to
the field. Sounds easy argggghhhh. I can't even get to the point of
opening the new browser window.

Any advice suggestion would be reeeeeaalllly welcome.
