Dynamic Stamp in Adobe Acrobat

Hi,

I want to create a Dynamic Stamp within Adobe Acrobat Pro DC to use for PDF Files. this stamp has the following functions,
1- Auto-Populate Current Date
2- Pop Up for adding Field Values
3- The date field is also editable ( I added the Text field for it).
I used the following javascript but didn't work. For the script, a Notepad file is attached.

Kindly help with this as soon as possible. 
Thanks!
