Select block by parameter

Hello,

is there any lisp for quick select block by custom parameter?

For example, select all block that have one of these two parameters (mirror parameter in block):

I have some lisp that is selecting by attributes fields, but it is not working for this:

Can't find there what I need. For me, I "only" have to select (or just count) block by its flip state (drawer in block on the left or the right side).

Sorry that my lead didn't work out.

I've lost track of exactly how I got from that discussion to the program I use now, but in any case, here's a copy of the LISP file. I hope it proves to be useful.

Thanks for that lisp!

Still no luck, this is what I need, but for some reason it can't read flip state. I also tried to rename my flip states to 0 or 1, like in lisp reading but nothing selected.
I will attach sample .dwg, I just need to select all desks with drawer on the left, or the right side.

With the db in your drawing, it doesn't work for me either.

I notice that the block's properties look different in the Properties palette, compared to how they appear in the SSD dialog box.

In the former, the options for the "drawer" property (which is a "flip") appear as "left" or "right":

But in the SSD dialog box they show up as "0" or "1":

I don't know what would cause them to appear differently in the two places, but it seems that perhaps SSD is looking "deeper" into the db than Properties does.

The "flip" property also has the same options ("0" or "1"). I don't know why this would cause a problem, but maybe it's something (for someone) to look at.
