Variaudio in Cubase 5 help

Hi guys so I’m pretty new to recording and I recently started testing out variaudio in Cubase 5.
It seems easy enough to navigate but I’m having trouble with the pitch quantize tab and the other tab beneath it (forgot it’s name at the moment) when I click inside the boxes to drag the quantize amount and nothing happens the slider doesn’t appear at all. Don’t know if this makes any sense but I’ve watch tutorials online for this but mine is just not active I guess, is there something in preferences that I need to get corrected or??
