Open hidden layers code is making me click twice to open

[monaya]

I have this code to show and hide layers that are all initially hidden.

It only works if you open and close layer 1 and then go to open layer 2.

The problem is I'm using this for multiple layers so when you open layer 1 and try to open layer 2 it makes you click twice for some reason even though it's not closing layer 1.

I don't want it to close the first one anyway, but I want it to go smooth, like open layer one and open layer 2.

<script type="text/javascript">
function toggleLayer( whichLayer )
{
var elem, vis;
if( document.getElementById ) // this is the way the standards work
elem = document.getElementById( whichLayer );
else if( document.all ) // this is the way old msie versions work
elem = document.all[whichLayer];
else if( document.layers ) // this is the way nn4 works
elem = document.layers[whichLayer];
vis = elem.style;
// if the style.display value is blank we try to figure it out here
if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined)
vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none';
vis.display = (vis.display==''||vis.display=='block')?'none':'block';
}
</script>



<a href="javascript:;" onClick="showhide('layerone');return false;">show it</a>
<div id="layerone" style="display: none;">layer 1</div>


<a href="javascript:;" onClick="showhide('layertwo');return false;">show it</a>
<div id="layertwo" style="display: none;">layer 2</div>

It seems to be working now. I'm double checking. I think I was using a different script that was causing the error
