I am using version ASP version 5.2

when i type in this code it gives me javascript errors

 

<img onmouseover="ad.src='/oxygene/uploads/images/back2.gif'" onmouseout="ad.src='/oxygene/uploads/images/back1.gif'" src="/oxygene/uploads/images/back1.gif" align="right" border="0" name="ad">

You can type it into the online demos and you get the same error, just different line.

How do i prevent these error from popping up?

Thanks
