Passing variables between URL

[glennjamieson]

no this is correct.  it does work outside of the cms.  it brings up the persons details, like it should do.  one guy said yesterday:

Just watch your URL.
It seems to be that you use the internal pretty-urls, don't you?
So i believe that because of the internal url-rewriting of CMSms core the CMS searches for a page called "staffDetails?staffID=X".
That means the system wants to load "index.php?page=staffDetails?staffID=X"
And this is no valid page alias.

does this make sense to you?  i think this is correct as the system is searching for a page that doesnt exist in the database. 
thanks
