I use Bluehost and the Form Builder works flawlessly for me.
To upload without filezilla log into your cpanel and scroll down to the File Management section and select File Manager.
From there select the Document Root for: for the domain you wish to work with.
Now you can use the tools across the top of that window to get your files uploaded.
Next place the script provided by the Form Builder into your page and publish. Preview the site and see if the files were uploaded to the proper location.
Good Wed Morning Mr. Rohloff,
You mentioned "Document Root" for the domain you wish to work with. How do I recognize the "Document Root"? Exactly what do I look for so I will know I have the right file? Thank you so much.
