Please help modify this Block Counter

[troggarf]

So I have tried Lee-Mac's 2 block counters. I don't want another Block counter. I do however want to understand how to modify this Block Counter that I found. I don't remember where I found it (it could have been from here @ cADTutor).

I made a change in some of the table heading from Vietnamese to English. However, I want to know how to delete a column (maybe 2). And add a total option that gives a total of all of the blocks.

I don't want another block counter because I like how this one asks for the text height and allows for a selection set by either picking individual blocks or by a window (I have no need for a global block counter).

I would like to get rid of the column "Don vi" and possibly the first column. I have tried commenting out ( some lines but that doesn't seem to work.

Thanks for any help
