I hate divs and javascript [Resolved]

[ober0330]

Everytime I do this, it doesn't work. All I'm trying to do is toggle between 2 divs.

Script:

function toggle() { 
// DOM3 = IE5, NS6 
document.getElementById('div1').style.visibility = 'visible'; 
document.getElementById('div2').style.visibility = 'hidden'; 
} 

function toggle2() { 
// DOM3 = IE5, NS6 
document.getElementById('div1').style.visibility = 'hidden'; 
document.getElementById('div2').style.visibility = 'visible'; 
}

Call to them:

echo "<br><br><input type=radio name=opt value=1 onclick='toggle()'>Specify Test";
        echo "<input type=radio name=opt value=1 onclick='toggle2()'>Specify Cell<br>";
        echo "<div id=div1 style=visibility:visible>testtesttesttest</div>";
        echo "<div id=div2 style=visibility:hidden>test2test2test2test2test2</div>"; 

IT WON'T WORK AND I MIGHT PULL MY HAIR OUT.
