I am trying to create my first form, but I am having trouble with it displaying properly. When I add a field set, there is a break in the graphic. What can I do to fix it?

Look in your CSS files for a stylesheet called “reset.css.” Line 59 of reset.css has this code: 

form div
{
     margin:10px 0;
}

It is that margin that is causing the gap between your heading and the form itself. Try setting it back to 0 and that should fix it
