Errors in a script

Hello all,

I’m working on the following script for Rhino. The script should calculate the areas of the element in each layer, and export these areas and its coordinates into an Excel file. It also should open a blanc Excel file and ask you where do you want to sabe it. It works more or less, but it has many errors.
-The first is that if there is any other Excel file opened in the computer, it doesn’t work, so it’s necesary to close all the Excel files before.
-The second problema is that if there is more than one element in a layer, it prints the properties of these areas separately in the Excel file, but the objective is that it prints the “total” area in each layer.

The script is the following. Could anyone give a helping hand to me? Thank you very much
