Hiding/Showing a Div with JavaScript.

[MrApples]

Yes that was the problem. I assumed JS was smart enough to not kill itself over a element not existing, guess not.

Working code:

function switchheader(id){
	if ( hcur != id ){
		document.getElementById(hcur).style.display = 'none';	
		document.getElementById(id).style.display = '';	
		if (hcur == 'logo'){
			document.getElementById('logo2').style.display = 'none';}
		else document.getElementById(hcur + 'b').src = '/styles/7M-v1/new/hb_' + hcur + '.png';
		if (id == 'logo'){
			document.getElementById('logo2').style.display = '';}
		else document.getElementById(id + 'b').src = '/styles/7M-v1/new/hbalt_' + id + '.png';
		hcur = id;
	}
}
