How to append the URL parameters to end of an HREF URL?

Hi,
Great plugin – but I am having problem implementing it within HTML – even with the syntax suggested.

For example, this link is not resolving: (ignore the white space I added so I can paste HTML code in here):

< a   h r e f=”mylink/?ss=”[urlparam attr=”value” param=’ss’]>

    Link text

< / a >

It is simply resolving to mylink?ss=

And not appending the value of ss passed via URL from the first page to the next page.
