PDF Forms - are custom calculation scripts and e-sign compatible?

Is e-sign compatable with PDF forms with embeded custom calculation scripts?

I have some really long PDF forms that make use of custom calculation scripts. Now the client wants to use e-signatures, but it doesn't look like e-sign is compatable with the embeded scripts.

The workflow I am trying to achieve is:

1) our agent prefills the contracts (this is where the custom calculation scripts do a bunch of calculations and populate fields to make the process fast and less mistakes, each contract is over 80 pages)

2) the prefilled contracts get sent by e-sign to the parties for signatures.

Is there a better way for me to set this up?
