X path expression

Users

Hi ,

I am getting a X-path error for this expression, If ( int(/data/month_calc)
< /data/month_calc , int(/data/month_calc) + 1, int(/data/month_calc))
saying "caanot handle IF function". This is a calculate condition in a
hidden value appmonth_calc.

month_calc is also a hidden value with calculate condition - number
((date(/data/visit_date)-date(/data/lmp_date))div 30.4).

Can anyone point out where is the mistake in this expression?

Thanks,
Ruchi

Ruchi,

I think this error is due to capitalization - 'if' needs to be all lower
case, otherwise CommCare will not recognize the function.

Best,
Will

Hi Ruchi,

In your "if" statement the condition you are checking is int(/data/month_calc)
< /data/month_calc.
It seems like you are comparing the same value, one converted as an integer.
Is it correct?

Kind Regards
