Expression rule for editable grid

Question

I have an editable grid when i go to add a row and fill it with some values and then clone the same row. I want to know that if the user clones or the data of both the rows is the same then the flag should be set to true and if the user clone the row and then change the data in that case set the flag as false. 
 can anybody help me to make expression rule. 
 
 Thanks

What have you already tried / what have you found to not be working? Can you provide your sample code so far and some screenshots and/or mockups of what you're hoping the form to actually show? 
 Your description is a little vague so it'll be hard for others to help you in any concrete way without quite a bit more detail up-front.
