    Asked by scot cockroft on December 16, 2011 at 11:58 AM

    I am just testing jotform.  When I went in to upload a .pdf file I get an error that says that it is an invalid extention.  I can't find in your faq where this is stated.

    While the upload field is highlighted, the context-sensitive top toolbar will show Extensions where you can edit the files allowed for uploading.
