I have a Adobe PDF form that requires three signatures. I have modified the form with Adobe LiveCycle Designer ES2 and added three digital signatures. the 1st dig signature is for the person filling out the form and the 2nd dig signature is for the certifying official and the 3rd  dig signature is for the authorizing official.

How do I modify the form so that after the form has been digitally signed by the 1st person, that the form cant be modified by anyone but allow the 2nd and 3rd digital signer to only sign the form?

cmiller,

How does this work for you?

Person1 completes the fields then signs. Once he signs all the fields lock except:
PersonName2, PersonSig2, Date
PersonName3, PersonSig3, Date2

Person2 then enters his/her name, date and signature. Once signed these fields lock except:
PersonName3, PersonSig3, Date2

Person3 then completes his/her fields. Once signed the whole document is locked.

I put a little javascript in preSign for Person2 and Person3 to complete the date field just in case people forget to fill it in. Once signed the field locks. The current date is entered into the field automatically.

Yes, sorry, I have been out for a few days.

Questions:
1. How did you set those settings? I have a few more forms that I would like to set up that way.

2. Did you use Adobe LiveCycle Designer ES2?

3. Where did you insert the java code?

Thanks,
-Chris

Something I just realized is that users that only have adobe reader cant digitally sign the form. Is there a way to fix that?

I submitted another question.

If you name the subform the code will work:
Info
So in the above form you attached, I renamed the subform to Form. Your code would then look like this:
form1.Form.Date1.rawValue = util.printd("yyyymmdd", new Date());

It did look like this:
form1.#subform[0].DATE1.rawValue = util.printd("yyyymmdd", new Date());

When fields are on different subforms, you need to specify the full path to the field you are trying to update. If the fields are on the same subform then you can just use:
Date1.rawValue = util.printd("yyyymmdd", new Date());
