Would a Reset Form button work?

Glad it worked for you.  Builds your confidence with the software when you can get it to work.

Take a look at this;   http://www.acrobatusers.com/tutorials/2007/js_list_combo_livecycle/Different approach than the country script but easier when you have multiple drop downs

With your form open, look in the hierarchy.Top item:  Form1Now identify the subform that contains your radio button list Designer defaults to:   (untitled Subform) (page1) -In my example I re-named it Subform1Now identify the name of your radio button listPlug those into the script

Add  a little to the script:xfa.host.resetData("form1.Subform1.RadioButtonListName");

Make the invoice a three page form.  Each page is identical with exception of one text field:Page 1 the text field is "Original"        2                        "Copy"        3                        "*****"

3 buttons:  YES - NO - CLEAR.Script is on the CLEAR button.In design mode, click on the CLEAR button and in the scripting window enter:    xfa.host.resetData("RadioButtonGroup Name");.Use Java Script and select "click" from Event drop down

Here's a link to a detailed description and the required script:http://www.javascriptkit.com/script/script2/multiplecombo.shtml

See this thread:  http://forums.adobe.com/thread/479845?tstart=90Varma's response with the script worked for me. Requires using variables and not being a programmer I found confusing but doable
