Calculate two fields and autopopulate sum

[bindu999]

Hi,

    I'm using client script to calculate the value of a+b and get total sum value in the single line text box. This script is not working for me. can you help me

 I'm using 2 select box'es 

a Select Box has option yes or no  (Yes value as 10 ; No Value as 5)

b Select Box has option yes or no (Yes value as 10 ; No Value as 5)

I'm using C as a single line text box I need to get the score of what the user selects.

If Select Yes in A; Yes in B; 

It should autopopulate C as 10

Client Script:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
var xyz ='';
var X = g_form.getValue('a');
alert('a');
var Y = g_form.getValue('b');
var Z = g_form.getValue('c');

xyz = X+Y+Z;

g_form.setValue('score', xyz);
alert('xyz');

return;
}

}

Please Help!!

Thank you!!!

One more point:

Your are changing three fields a, b, c and you are writing onChange client script on 1 field.

It will only work onChange of one field. You'll have to write 3 same client script if you want to get sum of all these 3 fields in real time.

Better way for this will be to write an After update Business Rule and set the field once you update the form:

Your BR script will look like :

var total_score = parseInt(current.a) + parseInt(current.b) + parseInt(current.c);

current.setValue('score',total_score )
