Cannot save embedded pdf file in pdf form - you cannot save the form

[NKB0609]

I have a PDF form which has another pdf form as an attachment.,

Idea is that if a certain criteria meets, user can open this embedded form and fill it out and save.

Now I am stuck at "Please fill out the form.  You cannot save the data typed into this form.  Please print your completed form if you would like a copy for your records" in acrobat reader. I have changed the file type using acrboat dc to "save as other - Reader extended PDF - Enable forms fill in & save in acrobat reader, however nothing changes. I am using Acrobat DC version.  Would really appreciate your help in this as i want the user to save the attachment within the form itself afetr making changes without having to reattch the document.  If there is a way aroud it using a script, please assist if that's the case.

You cannot save a modified attachment with Acrobat Reader.

You should use a spawned page instead of an attachment.

Many thanks for your response.  Can you please help me with the code to spawn these pages.  Please note that this fole contains scripts and multiple check boxes and formulas.

Hope spawing it will not temper the script.

Many thanks for your help.

You will find many samples in this forum by searching "spawn" and/or "templates".

Don't hesitate to ask for help if you can't find what you need.
