I am trying to fill out this form but it doesn't allow me to input any
data. It doesn't even react to the Tab key. I looked at the document
properties and it says that "Filling of Form" was allowed. I also looked
at the answer for the other question like this, "How to input data on an
existing PDF form," but that didn't really help me. I've had this
problem before with other pdf documents. Can you assist me? Thanks!
