If you want Subscript[\[Epsilon], 11] to be an anonymous function of 2 variables (r and theta) you may e.g. write: Subscript[\[Epsilon], 11] = Subscript[\[Epsilon], rr][#1, #2]*Cos[\[Theta]]^2 + Subscript[\[Epsilon], \[Theta]\[Theta]][#1, #2]*Sin[\[Theta]]^2 - Subscript[\[Epsilon], r\[Theta]][#1, #2]*Sin[2*\[Theta]] &;

Please read how to define anonymous functions. Then consider your definition of Subscript[ϵ, 11]. This is a function that does not use its arguments.
