Need Help: I need a check box to auto fill a set value in separate text field.

Question

Hi, this is my first time with inserting scripts into a PDF Form.
We have a form that requires the user to check a box regarding medical conditions they have (i.e. Asthma, Diabetes, Hypertension).  Later in the form, they have to type out the same condition into a text box. (I know stupid to double document, but it is required).  Is there a script that will auto fill the text box when they check the box?  For example, if they check asthma, the text box on a later page in the PDF will say "Asthma, controlled."  Is this possible?
In addition, if they don't click Asthma, and do click Diabetes, could it add Diabetes to the first text box, but if they check both, it would add Asthma to box 1 and Diabetes to box 2?
Any help would be GREATLY appreciated.
I'm using Acrobat 9
Thanks!

Answer 1

Hi, I'm staring at the code trying to make it work for my needs, which are similar to Austin's.
I have a 16-page form with 2,988 checkboxes in the entire document (a little over 200 in each page besides the first and last page). The last page contains a textbox labled Summary, and it should provide a summary of all the items checked in the document. Theoretically only one page will be populated at a time, so there will be no more than 200 checkboxes checked in the entire document.
Is it possible to use the same code? And do I just put the code under the text in the script that reads:
form1.SummaryPage.SummaryText::calculate - (JavaScript, client)
The JS I am trying to get to work is the following from a post above.
// Custom Calculate script
(function () {
    var i, v, s = "";
    // Loop through the 2988 check boxes
    for (i = 1; i < 2989; i += 1) {
        // Get the value of the current checkbox
        v = getField("checkbox " + i).valueAsString;
        // Concatenate check box value to string if not deselected
        if (v !== "Off") s+= v + "\r";
    // Set this field value
    event.value = s;
