IE 4.0 error using the raiseEvent property

[dkwong]

I'm using the following code to communicate between a scriptlet and its parent ASP page:

--in the scriptlet:

Sub FireEvent (sEventName)
window.external.raiseEvent sEventName
End Sub

called using the following command: FireEvent &quot;<name>&quot;


--in the parent page:

Sub sclScriptletName_OnScriptletEvent(txtEvent, eventData)
if txtEvent = &quot;<name>&quot; then
...
end if
End Sub


Does anyone have any idea why there would be the following error in IE 4?

Error: wrong number of argumnets or invalid property assignment: 'window.external.raiseEvent'

This works in IE 5 & 6, but not in 4. It seems that the &quot;eventData&quot; parameter in the onscriptletevent is needed or it won't work in 5 & 6. This needs to work in all three versions of IE.
