How to get sum of RadioGroups in DA

 

I have 3 RadioGroups, i would like to get the sum of Radios in other Item "Results", I made a DA with PL/SQL block that works, but I just get the result only if all 3 radiogroup are select

This happens due to the handling of NULL values in Oracle. NULL values are neither equal nor inequal to any other value, so none of the conditions in lines 11-13 are true. If any value in a numerical expression is NULL then so is the entire result, which is what occurs with the total calculated in line 17.

The required approach is to convert the NULL values to 0 using the COALESCE or NVL functions in a PL/SQL Expression Set Value DA:

coalesce(to_number(:p4_radio1), 0) + coalesce(to_number(:p4_radio2), 0) + coalesce(to_number(:p4_radio3), 0)

and if it is possible to do with javascript

Assuming the values are integers, the equivalent JavaScript expression using the ternary operator is

parseInt($v('P4_RADIO1') ? $v('P4_RADIO1') : 0), 10) + parseInt($v('P4_RADIO2') ? $v('P4_RADIO2') : 0), 10) + parseInt($v('P4_RADIO3') ? $v('P4_RADIO3') : 0), 10)
