Count the fields not including the zero value of the fields in crystal reports

Question

I'm using Crystal Reports 2008. I have an output like this:

  Customer    Total Amount         Jan     Feb    Mar    Apr    May    

   A           20000               1000    2000   5000     0    7000
   B           15000               5000    7000   3000     0     0
   C           18000               8000    5000    0     8000    0
   D           5000                5000      0     0       0     0

How can I make count the fields from Jan to May without the zero field value? So the output will be like this:

  Customer    Total Amount         Jan     Feb    Mar    Apr    May      Count   

   A           20000               1000    2000   5000     0    7000       4
   B           15000               5000    7000   3000     0     0         3
   C           18000               8000    5000    0     8000    0         3
   D           5000                5000      0     0       0     0         1

Thanks..

Create a formula for your Count columns something like this

IF {table.Jan} <> 0 THEN 1 ELSE 0 +
IF {table.Feb} <> 0 THEN 1 ELSE 0 +
IF {table.Mar} <> 0 THEN 1 ELSE 0 +
IF {table.Apr} <> 0 THEN 1 ELSE 0 +
IF {table.May} <> 0 THEN 1 ELSE 0
