I've created a fillable form and have inserted 3 sections. At the end of section one an employee is required to add their signature. In that signature box property I have set it so that once the signature is applied all form fields selected become read only. The form is then passed onto the next employee to fill out section two and I don't want them to be able to edit the first section of the record. etc. The final signature in section three should lock all form fields.
These signatures lock the fields from being able to be edited, however it's kind of pointless when anybody after signing the document can hit "Clear Form" and all the form fields are removed - hence leaving me with a document that contains no records, just signtaures.
How can I prevent the use of "Clear Form" from being used?
