Can’t figure out how to remove the border around my Form

First thing I see kinda stopped me right away: Take a look at your wp-content/themes/greening-101/dd-formmailer-plugin.css file. It’s filled with page source instead of the dd-formmailer-plugin.css contents… Try deleting that, re-upload and report back?

it’s the fieldset tag.

look in your CSS file for the fieldset tag. if it’s not there, add this:

fieldset {border: 0;}

if it is there, just add the border: 0; to it.
