Enable Auto save while clicking button in PDF

Guys,

I have designed a form using LiveCylce designer ES2.

I have tired to write a code that will save the PDF automatically into the folder.

However it gives only popup. I have enable the user rights and try to open the pdf in Reader and attempting to click and save. But it not works.

Hope I have explained my concerns clearly.

Can you please guide me to get into the right direction.

Thanks

Siva
