I'm having trouble getting the getElementById() command working properly, I've tested in various browsers and looked around to see if I can find the issue elsewhere and compared my code with others and I can't see a reason why it wouldn't work...
Here's the code in my header:
function header(x,y)
{
document.getElementByID(x).style.display = 'block';
document.getElementByID(y).style.display = 'none';
}
And the HTML:
<form action="blah.html" method="post" enctype="multipart/form-data" name="adevent2">
<input type="radio" name="heads" value="image" checked="checked" onselect="header('usefile','usecolour')" />Use background image<br /><br />
<div id="usefile" style="display:block;">
<label for="file">File to upload:</label>
<input id="file" type="file" name="file" /><br />
</div>
<input type="radio" name="heads" value="colour" onselect="header('usecolour','usefile')" />Do not use background image<br /><br />
<div id="usecolour" style="display:none;">
<input type="text" id="headbgsample" name="headbgsample" size="1" value=""><br />
</div>
