here's java functions:

// -------------------------------------------------------------------
// moveSelectedOptions(select_object_From,select_object_To)
//  This function moves options between select boxes. Works best with
//  multi-select boxes to create the common Windows control effect.
//  Passes all selected values from the first object to the second
//  object.
//  You can also put this into the <SELECT> object as follows:
//    onDblClick="moveSelectedOptions(this,this.form.target)
//  This way, when the user double-clicks on a value in one box, it
//  will be transferred to the other (in browsers that support the 
//  onDblClick() event handler).
// -------------------------------------------------------------------
function moveSelectedOptions(from,to) {

		}
	}

//  Move all options from one select box to another.
// -------------------------------------------------------------------
function moveAllOptions(from,to)

}

try

if(count($_POST['selectedFields'])) $fields = implode(', ', $_POST['selectedFields']);


$sql =" SELECT $fields FROM table1";

and change part of form to

<select size="20" id="list" multiple name="availableFields[]" onDblClick="moveSelectedOptions(this.form

['availableFields'],this.form['selectedFields'])">
<option value="item_1">Item 1</option>
<option value="item_2">Item 2</option>
<option value="item_3">Item 3</option>
<option value="item_4">Item 4</option></select>

name must have [] on end then can have more then one value

you need to select values what you want to form pass
