its work on previous i attached file but  now it did not work for this atached file ; error: no function definition: GETAREA

ah i forgot that in the messasge. Put this at the end:

that is because there are layers that get evaluated without any objects/area in the drawing. 

I editet the post you marked as Solution to take this into account, see if this works.

THIS CODE I RUN SOME TIMES ITS WORK FINE MANY TIMES  Command: FSI
; error: no function definition: GETLAYERAREA

[EnM4st3r]

in line 48 you try using a function called "getlayerarea". But this function is not defined in the code.
I guess you want to use the "getarea" function here?
