Copy Date value from Design Page to Master Page

Hi All,

I have a table with one of the columns as the Date Field in Design Page. I have one Date Field in the Master Page.

As and when user enters the date value in the table in the Design Page ( Content Area ), one of date values must be dynamically populated to Date Field in Master Page.

I tried with different paths but its seems not be working. My concern is, Can we copy a value from Content Area to a field in Master page?

Please share your thoughts and Suggestions...

Regards

Jay
