User Permission Issue

Dear All,
Could you please let me know whether there is an issue with assigning User Permissions?

Need urgent help on this.
Thank you so much.

Why do you ask? Did you encounter a problem? If so, describe it.

Yes as shown there, assigned user name is in gray. But I have given full access. hope this helps.

Thank you @Tut for quick response. Now its working. Problem seemed to have been with saving the creation of permission.
Thanks a lot.
