I guess I was too vague in my issue for Replybot to be effective.

 

My goal is to monitor blocks with attributes in my drawing. When the attributes change or blocks are added or removed, I need to make a total count of the attribute values. I can do this using Data Extraction and a table dropped into the drawing just fine if the number of blocks do not change. If I add or subtract blocks the range of the sum does not add up correctly. 

 

If I use Data Extraction and send it to an Excel file, I have more issues because the Excel file that AutoCAD extracts to will not let me do a sum of a column unless I convert the values to number. It seems that there is some sort of error that shows the number, but does not allow formula evaluation on them. The other issue I have with the Excel file is that if I add or remove blocks, I have to output a new data extraction and I would have to recreate a sum of the column every time.

 

Here is a screen cast of my issue
