I have created a button to run the following actions:
var text1 = document.getElementById(id_of_first_text_field);
var text2 =document.getElementById(id_of_second_text_field);
text2.value = text1.value; // copy value of Ist field into second Field
This is to try to copy a numerical vale from a text field (Text1) to another text field (Text2)
3. Mouse Down > Reset a form (all fields except Text2)
2. This is a function, you would need to call it (though it won't work)
Autosave is a serious problem, because you can download PDF files from the internet - they are not free to just save where they want.
