impossible to find project or library

[carry]

Hi.
I'm trying to upgrade to autocad 2012 32 bit
I have a problem with macros in vba.
I downloaded the files for vba, part and vba works.
the problem lies on these lines:

set fs = createobject("scripting.filesystemobject")
set a = fs.createtextfile("c:\lsp\temp\getprofilo.dat", true)
a.writeline userform1.combobox1.text ' 0 sectionname

When it comes to fs= I'm mistaken:
impossible to find the project or library
What should I charge?
Thank you for your help
Greeting

I answer, I have failed to declare that fs is an object
dim fs as object
dim a as object

before it worked even without declaring null,
now vba is more demanding....
