Creating a PDF with forms that auto-calculates

Postby Faust » Tue Aug 10, 2010 12:49 pm


I currently make my company's quotations using latex and I have included checkboxes from the hyperref package, so people can choose which options they want -similar to Dell's website where you can configure your PC-

I would like the PDF to auto calculate the total every time someone
makes a change, is this possible using latex? What package should I use?

If someone has plug 'n play javascripts or something easy I can use I'd be happy.

• If you create your PDF form latex using distiller you can use the eforms package available at The eforms can can create calculation fields. See the AcroTeX PDF Blog #25, titled “Processing Acrobat Forms using JavaScript, Internal Processing of a Field, Part 5: The Calculation Tab” at All PDF forms seen at the AcroTeX PDF Blog were created with AeB (, using distiller. Blog #25 contains many examples of automatic calculation.
• If you use pdflatex and have Acrobat (not Adobe Reader, but Acrobat), you can use the UI (user interface) to create the auto calculation. Blog #24 would be helpful again.

Don Story's packages are very useful. I hope this helps,
