onmouseover object doesnt support property or method error
I am trying to develop a text editor system for a forum board I am creating, something similar to what sitepoint used to have when adding new topics/replies.
<input type='button' accesskey='u' style='width: 30px' value='URL' name='btnHttp' onClick="tagInsert('link');" onmouseover="help('u')">
Object doesn't support this property or method.
Please help me. I'm about to pull my hair out.
