Can only move part of my searchbox. HELP!!

Hi I am having difficulty in moving my search bar into the bottom right area of my header. The search box seems to be split into three components in my style sheet as shown here –

#header form {
		position: relative;
		top: 0; left: 0;
		float: right;
		position: relative;
		top: 5px; left: -49px;
	}
		#header form input {
			font-family: Georgia;
			font-size: 1em;
			float: left;
			width: 220px;
			margin-right: 5px;
			border: 1px solid #ffffff;
			top: 45px; left: -25px;
		}
		#header form button {
			text-indent: -9999px;
			width: 18px; height: 18px;
			border: 0;
			float: left;
			background-color: transparent;

Problem is I can move one of the components to the position I want without any problem (header form) the other two components just stay where they were.
