form does not validate
As per the FAPI the element textfield has no name attribute 

Available Properties are 

#access, #after_build, #ajax, #attributes, #autocomplete_path (default: FALSE), 
#default_value, #description, #disabled, #element_validate, #field_prefix, #field_suffix,
 #maxlength (default: 128), #parents, #post_render, #prefix, #pre_render, #process, #required,
 #size (default: 60), #states, #suffix, #text_format, #theme, #theme_wrappers, #title, 
#title_display, #tree, #type, #weight


I am not sure about the reason that the form is not validating, Excited to know the reason.
