urgent - block is not defined error in autocad
when i try to add block from one database to other empty database i got an error of undefined block error when i open it into autocad 2007.
when i audit the oddbdatabase it shows me ok.
i added herewith that block file for reference.
i added herewith code for reference.

it is not working
code is working for all other blocks which do not have attributes.
but it is not working with block which i specified here with.
i received undefined block error when i opened it into autocad.
