You can use Select in Field trigger while traversing to different sheets...
The syntax you can use is
Suppose In sheet 1 You have selected Year as 2016 and Month as Jan, Feb
The in Sheet 2 , you should write an action on Sheet activate,
1. Select In Field > Field Name> Year_Rate, Value> '('&concat(distinct Year,'|')&')'
2. Select In Field > Field Name> Month_Rate, Value> '('&concat(distinct Month,'|')&')'
Similar actions can be defined at sheet 1 also for traversing in reverse manner.
Hope this help you out.
