getting error in data store memory while using global variable

hi.. iam Senthilkumar. am new to simulink, while using it i frequently getting the error whenever i declare a variable as global "Data store memory with name 'Angle1' was not found for the corresponding block", but actually am declaring the Angle1 as a data store memory in edit data which is an option provided in the tool bar. but it is still showing the error.

function Angle = Angle()

global Angle1

Angle = Angle1;

end

what it is actually expecting me to do in the name of 'data store memory was not found'.

please help me with this..

thanks in advance
