Filling out form with pre-determined values

Question

I am new to LiveCycle. I want to set up a form where if a person hits a button or check box, it fills in the form with predetermined variables. I want to there to be several different buttons/check boxes which if selected fill out the form with the predetermined values. These values would be different, depending on the check box/button selected.  Is this possible?
Just to help understand a little more, I am designing a medical prescription form.
If the practitioner selects 'Option A' I want it to automatically fill out the required fields in the rest of the form with the predetermined values (set by me).
Similarily if the practitioner selected 'Option B', it fills out the form with another set of predetermined values.
Hope this makes sense.
Thanks

After looking at your form, I understand what you were going for.  You want several fields prepopulate values when you select either Option A, Option B... and so on.  Here is the script I use for the different fields, I would also suggest adding the same script to the initialized event so you can save the state of the form after it has been changed.
From a Drop Down - JavaScript Change event 
if(xfa.event.newText == 'Option A'){
optionText.rawValue = "This is option A";
optionText2.rawValue = "This is option A value";
optionText3.rawValue = "This is option A";
optionText4.rawValue = "This is option A";
optionCheckbox.rawValue="0";      //0= unselected  1=selected
optionRadio.rawValue = "Option A";
if(xfa.event.newText == 'Option B'){
optionText.rawValue = "This is option B";
optionText2.rawValue = "This is option B value";
optionText3.rawValue = "This is option B text";
optionText4.rawValue = "This is option B";
optionCheckbox.rawValue="1";
optionRadio.rawValue = "Option B";
From a Radio Box - JavaScript Click event  (make sure you define your values)
if(optionRadio.rawValue == 'Option A'){
optionText.rawValue = "This is option A";
optionText2.rawValue = "This is option A value";
optionText3.rawValue = "This is option A";
optionText4.rawValue = "This is option A";
optionCheckbox.rawValue="0";
optionDropdown.rawValue = "Option A";
if(optionRadio.rawValue == 'Option B'){
optionText.rawValue = "This is option B";
optionText2.rawValue = "This is option B value";
optionText3.rawValue = "This is option B text";
optionText4.rawValue = "This is option B";
optionCheckbox.rawValue="1";
optionDropdown.rawValue = "Option B";
From a Button - JavaScript Click event
optionText.rawValue = "This is option A";
optionText2.rawValue = "This is option A value";
optionText3.rawValue = "This is option A";
optionText4.rawValue = "This is option A";
optionCheckbox.rawValue="0";
optionDropdown.rawValue = "Option A";
optionRadio.rawValue= "Option A";
I would attach a sample form, however I can't see where to upload it on this forum.  I will email you the form.
Suggestion on your form:  Make sure your form fields have unique names in the hierarchy (Shift + F11).
