How to get Values using between operator in webi variable

Hi Experts,

I have set of data as follows:

Tracks     Manager     PaymentDays

9011          A1               2

9012          A2               6

9013          A1               9

9014          A3               3

9015          A4               12

9016          A3               14

9017          A2               7

9018          A5               1

9019          A6               10

9020          A5               4

So I want to see how many Tracks we have between 0 - 5 days how many in 6 - 10 days and in 11 - 15 days by Manager.

Manager  |   0 - 5 |     6 - 10 |     11 - 15

A1               1          1               0

A2               0          2               0

A3               1          0               1

A4               0          0               1

A5               2          0               0

A6               0          1               0

How can I create 3 different variables for above columns.

eg. Variable that I created but its not working;

Var1(0 - 5) = (count([Tracks];All) where (PayementDays between (0;5)) foreach (Manager))

But it is giving total number of PaymentDays of every manager.

Please help me in creating variable.

Thanks.
