Thanks for your response Scott.
I am working in ADOBE LC ES. The reason I am using execdialog is that my form needs an interactive pop-up window. The user has the ability to select from a set of check boxes and on clicking "OK", the selected values are displayed in a text field on the parent form. This functionality is working prefectly when a reader extended form is viewed in ADOBE Reader. The only problem is the Title to the pop-up window which does not change even though the code has been added to change it.
Can an interactive pop-up window with checkboxes and text fields be developed using xfa.host.messagebox()? I was of the impression that execDialog is the only way.
Thanks
