How to give Limits & Fits Dimensions (Tolerance Grade Dimensions) in UG NX 7.5?

I am trying to give Tolerance Grade Dimension for e.g. Ø10H7 on my drawing but the limits and fits dimensions is not highlighting. I do not understand how to make it active. Please advice.

Thanks in advance.

Right click on the dimension, click the Style button, wait a second, click on the "Dimensions" tab close to the top hover over the button with "1.00" in it and the word "No Tolerance" should appear. CLick on the blue chevron to change the type of tolerance you want to use, and the other fields will un-gray and become avaliable to edit.
