>Can you provide more details?

Hi Sergey:

Thank you for your kind response.

The purpose is to calculate an age premium, which is as follows:

- If age is less than 2 yrs , then it is 25% of the rate for a code
- If age is greater than 2 and less than 6, then it is 10% of the rate for a code

Codes that are eligible for this are 003 to 011C to T and some other single codes.

What I had in mind was:

Do Case
  Case 1
    If msFeeCode is between 003 to 011C to T
      and age less than 2
        Do this...
    else
      if msFeeCode is between 003 to 011C to T
        and age is greater than 2 but less than 6
          do this.....
      endif
    endif
  Case 2
    ..........
Otherwise
EndCase

Thanks Sergey
