Getting the number of objects based on selection and filtering by block name

[gustavobernardi]

Why I can't have the number of objects with this code:

(setq selectiopanel (ssget '((2 . "Painel Fotovoltaico" ))))
(setq n (sslength selectiopanel))

The selection works fine, but the n value returns nil. And on the command line screen it returns this error:

:CALLBACK-ENTRY.6 (:CALLBACK-ENTRY)
:ARQ-SUBR-CALLBACK.3 (nil 0)

Error: bad function: <Selection set: 92>

TIA

Re-open the file or open a new one, or better re-open Acad, still a problem with ONLY these two lines?

You have to get blocks 1st then 2nd order name

(setq selectiopanel (ssget '((cons 0 "Insert")(2 . "Painel Fotovoltaico" ))))

Thanks for the answer

I've tried it before, and it was unsuccessful. I don't know what was wrong, perhaps some part of the code had broke some definition of my AutoCAD and it was recovered when I restarted.

I don't know if it have a further problem, but it is working without verifying if it is a Reference Block.
