Ah, ok. That makes sense then. By checkbox I thought you meant a checkbox you can electronically interact with. If you do have a flat, non-form PDF then OCR would be the only way.
One potential solution is to pre-process it with Acrobat and have it guess form fields (this actually works fairly well in some cases). THat would turn it into a form PDF. If you send me the form I can take a look. Duane Nickull *********************************** Technoracle Advanced Systems Inc. Consulting and Contracting; Proven Results! i.
