Service Duration Value

Question

Hello, 
 I am trying to implement a formula: ifElse(contains($arr_yes_no_c,"Y"),divide($sub_new_arr_c,"service_duration_value"),"") 
 
 However, I am getting an error message: Unknown field: service_duration_value 
 Anyone knows the standard name for Service Duration Value? 
 
 Thanks!

This field is not Studio enabled by default. In order to reach it you can configure the attribute formula via Extended Vardefs instead. 
 
 $dictionary['theClass']['fields']['the_field']['calculated']='true';
$dictionary['theClass']['fields']['the_field']['formula']='ifElse(contains($arr_yes_no_c,"Y"),divide($sub_new_arr_c,$service_duration_value),"")';
$dictionary['theClass']['fields']['the_field']['enforced']=true;
