Hi Rajiv,

Your solution gets the horizontal look that I'm trying to achive.

The user did come with more info.

>>>There are many Collegeid.

>>>There are many deptid.

>>>There are up to 900 regid. But no deptid will have more than maybe 10 to 15 regid.

So each row will have unique collegeid, unique deptid, and then several regid listed in the row. Or the regid for a particular collegeid deptid combination, may be null.

I'm beginning to think cursor is needed and have been reading about those and how to implement them.

I appreciate your insight.
