.... Hello, It is posible to write a function

.... I mean instead of write the rule template:    
....    driver.priorClaims 
.... write the rule template: 
....    driver.priorClaims("lastWeek")

.But I need to return a number or strign that matchs with the value of a cell in
the decision table.
.Any other idea?
 

Ok, you are right!

i have write the condition as:
 eval(driver.checkPriorClaims("lastWeek",$param))
and i have implement in Driver, checkPriorClaims(String period,int numberToCheck)

note, in case of the cell values will bew strings, the condition will be:
 eval(driver.checkPriorClaims("lastWeek","$param")), and the method in Driver
will be checkPriorClaims(String period,String paramToCheck)

Thank you very much.
