Re: Re: [xsl] Multiple select listbox as parameter

[<mfreeman@xxxxxxxxxxxx>]

Thanks for the reply Joe.  You have certainly maxed out my XSLT abilities.

Anyway, I added your code to my HTML file and for all your functions that set a new ActiveXObject, I get the following error:

'Automation server can't create object'

Originally I had all the ActiveXObjects set to MSXML2.FreeThreadedDOMDocument, so I tried that, but it crashed when I tried to set oParams.loadXML.

It sounds like I have some other problems here than just passing the parameter, huh?
