[TYPO3-english] how to retrieve querystring value

[Erich Specht]

Does anyone know how I can access querystring values from typoscript?  I'm
trying to pass a value to a USER script via the $conf object.

 

I tried this, but no luck:

 

page.10 =  USER

page.10 {

    userFunc = user_my_events->getSingleEventHTML

   uid = GP:uid

}

 

Thank you for your help.
