To calculate 'Frequency', we created logic to convert the code to a number. However, the code is not an option in Bonnie. Please advise. Thank you.
 
define function "DosesPerDay"(frequency Code ):
case ToInteger(frequency.code)when 229797004 then 1.0 when 229799001 then 2.0 when 229798009 then 3.0 when 307439001 then 4.0 when 396125000 then 1.0 when 307470009 then 2.0 when 396126004 then 0.67 when 307469008 then 3.0 when 307468000 then 4.0 when 396143001 then 0.34 when 396131002 then 0.5 else null end
