Option__c(picklist) This is picklist field which contains values (Yes/No) and default as Yes. This field(Option__c) should only be mandatory, when the field State__c(multi picklist) has selected as NY.

I have tried a Validation rule, it looks something like this,


  IF( INCLUDES( States__c , "NY"),
  1. IF(CONTAINS(TEXT(Option__c), "YES:NO") , IF( INCLUDES( States__c , "NY"), false, true), false)

Both are not working and also not allowing me to save on any conditions. Any suggestion please, Thanks in advance!!!

    How about AND(ISPICKVAL(State__c, 'NY'), ISBLANK(Option__c))?
