How to get old and new field value from model through snippet/javascript

Hi Huyen,  Thanks for your response :slight_smile: ,

Actually, i want to do further actions based on this comparison and user can change this picklist value multiple time during the process…

i had read the same query/problem somewhere in the skuid community support portal and that had provided some snippet code for it but the issue is that now i am not able to find that post. i don’t want to user UIOnly field as i need to maintain it always. 

Thanks,
Akanksha
