Javascript error - properties help?

[Patrick McHale]

Hi,

I have been trying to find the answer to why a javascript error occurs
because of this line.

The HTML line in question is:
var webterm = Components.classes["@PowerlanUSA/webterm;1"].createInstance();

The javascript error is:      Components.classes['@PowerlanUSA/webterm;1']
has no properties
                                        Source File:
file:///C:/Mozilla/Locations/NS6AHollis.htm
                                        Line: 7

Everything works - except I get this javascript error for some reason.

Can anyone help?

Regards
