Dear All,

I have a number of age, from 1 to 18 maybe a month and may be a year(month 1-11, Year 1-18), I want to put a condition of choice (year of month)  
If the age of the child in the months allows to give the option of the month and year until the number 11  
If the number 11 exceeds the option of the year only without the month.  
I hope that the explanation is clear

Hi Ahmed,

It sounds like an [if() function](https://confluence.dimagi.com/display/commcarepublic/CommCare+Functions#CommCareFunctions-if) will be able to accomplish what you are looking for.

Hi Ahmed,

I think the easiest way to configure what you are asking about is to actually have two different lookup tables, one which allows selecting month and year, and then one which only allows selecting year.

You can then use a hidden value to 'normalize' to a single value by using whichever one was valid.
