Hi V@no,
thanks for ur suggestion, but the usernames at my site do not have special characters . . .
I think there must be somethings wrong in the command or function to call the username to the table on the left handside . . . If possible, please let me know the code for this function, I will look into it to see any likely errors.
When I logged on my account at ur site, and edited the permission, the table on the left handside is full of username, while at my site it was empty . . . .
Thanks for early reply
