@Manju_Reddy_Kanughula - Make sure you have used the correct Index (As you have mentioned Column U in your code).
Also you have to increment the int_RowIndex value, while updating the value in next cell else it will over write in the same cell.

Try using write line and print the value of item.ToString and int_RowIndex+5.
