Staff Access to more than one dept

[jason]

OK I have created 2 depts. and 3 user groups. I some staff members to be able to see tickets for one dept and other staff members to see the other dept.

I would also like to have some staff that can see both.

So I have dept 1, dept 2. And I have group 1 in dept 1, group 2 in dept 2 and group 3 in dept 1 but I have the boxes checked to allow them to see the other depts.

Staff in this group cant see either. If I change the dept and group to one or the other they can see them.

Im sure I am doing something wrong but I am just no seeing it.

Thanks
Jason
