That should say "electronically fillable form fields". You need to use a tool like Adobe Acrobat to put form fields on top of the form that people can type into. Once you have that you can import into FormsCentral.
If you form does have that already then I would need to take a look at the file to see what the issue is.
I'm not sure I understand your response... this is the link to the form I am trying to import so the fields will be fillable....
This form doesn't have fillable fields. If you open it in Adobe Reader and click on a field you'll notice you cannot type into it. It "looks" like a form but you can't fill out the fields electronically using Adobe Reader. You have to overlay "field objects" on top of the form for people to type into it - this is done using Adobe Acrobat.
aa hah! I get it now. thank you so much!
