Calculating future date in a form

I was able to find someone who could help me, and this is the custom calculation script that was created for anyone else who may have the same issue (it works)!

  // Custom calculate script for "31ST DAY" field 

    (function () { 

        // Get date from field 

        var v = getField("ORIGINAL DISPENSE DATE").valueAsString; 

        // Get date from field 

        var x = getField("DATE DISPENSED").valueAsString;   

        // Convert string to date 

        var d = util.scand("mm/dd/yy", v); 

        // Convert string to date 

        var dx = util.scand("mm/dd/yy", x);    

        // Populate this field with the result 

        if (v) { 

             // Add 30 days 

            d.setDate(d.getDate() + 30);

            event.value = util.printd("mm/dd/yy", d); 

        } else { 

            if (x ) {

                // Add 30 days 

            dx.setDate(dx.getDate() + 30);

            event.value =  util.printd("mm/dd/yy", dx);

            } else {

            event.value =  "";

        }

            }

})();

You will need to use custom JavaScript. The question each of finding earliest date and add days or other period have been asked and entered many many times. You will need to convert the date strings values of the 2 fields to a JavaScript date object, you can use the "util.scand()" method., You can get the earliest date by comparing the results of the "getTime()" method of the date object. You can use the "getDate()" and ".setdate()" to add 30 days to the selected date object. You can then use Acrobat's "util.printd()" method to format the result.
