Not able to copy the value  into Input box which is in Record List.

  
Hi all, I have two Input Box  one is inside the Record list and other is outside the  list, what i want to achieve is to copy the value from the input box which is outside the record list into the inputbox which is inside the record list when clickiing on the button. 
Using java script i am trying to copy the value, but not able to get the ID of the Inputbox which is inside the record list.
Can you please provide me some solution.

Thanks Rajendra Singh
