I have a custom Object called Orders
My Project is to  update the Active Field (which is a picklist) has two values 'yes' and 'no'
Start date is less than today and end date is greater than today then Active field should be 'yes' otherwise 'no'.

I made this project with help of process builder and it worked fine,Let say that start date is something in the futuer for Ex:if today is 24th .I set the date as 26th in start date filed thn on 26th it should automatically become yes .

Please help me
