number combinations that may be in each row.and how many times this
combination occurs.is there a formula to do this? -- thanks wynb

You might be able to do something like:
=SUM(ISNUMBER(FIND("123",A1:J1000))*1) as an array where 123 is the number
combination you are looking for.
To enter a formula as an array, copy and paste the code into the cell, but
rather than hitting Enter, hit Ctrl+Shift+Enter.
Now this will only count each cell once. So if I use "123" then if I have
123 in A1 and 123123 in A2, it will only return 2 (once for each cell).

Something like this?
