Setting a Folder's CHMOD to 777

I am trying to set a folders CHMOD to 777, and it wont let me. it is faded out. there is a way to do it in the custom fashion but i cannot seem to figure it out. the reason i need to do this is so i can install a program called vwar. If you know hte command to change it to 777, tell me how and i will love you forever!!

SmartFTP is not able to recursively change the permissions of the files. But you can change the permissions of the directory in the list view. The list view is on the right side in the remote window. You tried to change the permission in the tree view (left side).

well. look at this... www.pwningpandas.com/vwar/install you csan proceed cause the folder need to be writable. and i cannot seem to do that.
