i created as folder in directory name not as txt formatt this is the real path /path/to/your/attachment/directory/ now did u get..............

No we don't you aren't being clear and grammar helps.
I highly doubt that "/path/to/your/attachment/directory/" is a real directory path.

Try creating a new folder in "public_html" called "attachments" then a path like:
/home/public_html/attachments/

problem solved thx to all...................

Glad it's working.
