Incrementing a cell contents by 1 based on a condition and previous value

The sheet "Award Code" contains the code which are constant numbers.

The sheet "Jan" contains some data

The sheet "Feb" is the main sheet where we want to get some work done.

Basically if the ELIGIBLE column (B) is YES, then we increment the value of the corresponding AWARD column (C) by 1 then what was for it in the previous ("Jan") Sheet.

So for example, in the "Jan" sheet the cell C4 had a value of "2". So in "Feb" sheet, since B4 is "Yes", C4 has gets a value of "3" (2 + 1).

One boundary condition is that if the value of AWARD col reaches "19" then it gets reset to "1" again.

Attach is the excel sheet.

Thanks
