How to set value in dropdown field



I am trying to set value on dropdown field based on value selected on cascade filed.

Example :-  If (cascade filed_parent  == Test1 && cascade filed_chiled == Test2 ) then ETA_field = 1day

How can I achieve this using SIL setup

Cascading selects are returning string [], so simply do like this:

if  (customfield_xxxxx[0]  == "Test1" && customfield_xxxxx[1] == "Test2" ) {
customfield_yyyyy = "1d";

Hope this helps,


Thanks Alexandra for the response but unfortunately this seems to be not working

What I did is :-

Created new Live Fields and point this script from SIL Manager

Is there anything I missed out please assist

 Also I want ETA_field should not be edited after set the value. ex. 1d

Hello Alexandra,

Please assist me how do i create Live fields configuration for above script work 

currently I am using 

Live Fields configuration as :-

lfInstantHook("customfield_16205", {"customfield_16205", "customfield_16302"}, "mandat.sil");



The fact that you're using it in live fields changes a little bit the situation.

You'll need two scripts: a hook and an execution script. They should look like below:

lfWatch({"customfield_xxxxx"}, {"customfield_xxxxx"}, "hook.sil");
lfInstantHook("customfield_xxxxx", "hook.sil");
string value = argv["customfield_xxxxx"];
string firstValue = substring(value, 0, indexOf(value, "|"));
string secondValue = substring(value, indexOf(value, "|")+1, length(value));
if (firstValue == "opt2" && secondValue == "2") {
    lfSet("estimate", "1d");
} else {

Don't forget to attach the live fields configuration on the project. :smile:



Thanks, Alexandra   you are awesome...!   the script is working flawlessly.

I really appreciate your help  thank you very much.

I'm glad it helps. In this case, please mark the answer as accepted. :smile:
