ocx events & HTML

Hello,

I insert an activex control into html page. I could use its properties, all method, only events that have no arguments, but events with arguments give the following error:

/////////////////////////////////
A runtime error has occured.
Do you wish to debug?
Line: 51
Error: Expected ')'
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

The event that causes the error is

////////////////////////////////////
<SCRIPT LANGUAGE="VBScript">
<!--
Sub AList1_EndVerScrolling(TextLineNumStart As Integer, TextLineNumEnd As Integer)
msgbox "Hello"
end sub
-->
</SCRIPT>
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

Can not I run events with parameters of OCX in HTML?

Thanks
