    Syntax Problems with Function

    I am trying to check for a fields value on load and hide certian
    controls based on it's value. I am having trouble with the "else"
    statement and the bracket placement. Help appreciated. Here is the code:
    <HTML>
    <HEAD>
    <SCRIPT LANGUAGE="JavaS cript">
    function HideTable(){
    var myform1 = document.form1
    var myform2 = document.form2
    if (myform1.txtNam e1.value == "Size Mix")
    document.getEle mentById("tn3") .style.visibili ty="hidden";
    document.getEle mentById("but1" ).style.visibil ity="hidden";
    document.getEle mentById("Table 2").style.visib ility="visible" ;
    else
    document.getEle mentById("tn3") .style.visibili ty="visible";
    document.getEle mentById("but1" ).style.visibil ity="visible";
    document.getEle mentById("Table 2").style.visib ility="hidden";
    }
    </SCRIPT>
    </HEAD>
    <BODY onLoad="HideTab le()">

      Jeesuz, don't you look at ANY documentation or ANY code before writing?

      What do you think the {} marks are for???? They enclose code. Enclose
      code between them that belongs in one *block*.

          Use jslint to correct this: http://www.crockford.com/javascript/lint.html
