Question : count by columns

Hi Experts,

My problem is a lot easier to illustrate than to explain so here it goes:
This is how my table looks like: A, B, C, D, E are departments

CustID | A | B | C | D | E |
123 | 1 | 1 | 2 | | |
456 | | 1 | 3 | | |
789 | 1 | | | | |
012 | 2 | 1 | 4 | 8 | 8 |
234 | | 2 | 3 | 4 | 5 |
345 | | 5 | 9 | | |

Now, I need to count how many CustID is in only 1 dept, 2, dept, 3 dept etc..

This is how my result should look like
Count | Frequency
1 | 1
2 | 2
3 | 1
4 | 1
5 | 1

Thanks!
