How to get parameters from URL?

[#1]

Hi,

I use this url to open IE plugin:

https://<server_name>/QvPlugin/opendoc.htm?document=<document_path>&ticket=<ticket>&userid=someText

I want to get the value for parameter 'userid' . I tried to get it using the system function QVuser() and not working, so now I want to get the value running a macro after OnOpen trigger is fired:

This is my script:

sub showUser

     varUser = ActiveDocument.Variables("userid").GetContent.string

end sub

varUser and userid are already defined as variables in the .qvw document, but after the macro is run the varUser string is still empty. What am I missing?

Thanks!
