Three tasks in Adobe LiveCycle Designer -- 2

Hello, I've got three tasks: 1) There is an existing pdf file, and a new pdf file. They have most of the fields are the same but some have changed exact. I need a well written sample to export the data from the first one, and import it into the second one. There are 4 data types to be transferred, and 12 fields in the first file, to be mapped 11 fields in the second file. a) Textbox b) Checkbox c) Listbox d) Custom made progress bar slider. - (This progress bar is already poorly written) 2) In my pdf, there are a two places you can attach a file, and there is a listbox under the file attachment button. Files should only be displayed in the associated list box, and filtered out in the other listbox. 3) Rewrite the progress bar slider. This bar is poorly written and the logic needs to be simplified. The look of the bar should stay the same.
