What is wrong with my CSS?

Question

I am trying to enter my names and input fields into the queue, but they are everywhere. http://prime.programming-designs.com/test_forum/viewboard.php?board=0

#formdiv{
    margin: auto;
    text-align: left;
    width: 30%;
}

.fielddiv1{

    background-color: #222222;
    border: 2px solid #333333;
    vertical-align: middle;
    width: 45%;
    float: left;
}

.fielddiv2{

    background-color: #222222;
    border: 2px solid #333333;
    vertical-align: middle;
    width: 100%;
}

.fieldtext{
    width: 100%;
    background-color: #333333;
}

Answer 1

Delete <br />which is between these two fielddiv1divs

Answer 2

You have <br>between divs containing them.

Answer 3

Wrap both of them (two divs with class fielddiv1) in one div. And also remove the line break between them.
