"Cannot evaluate expression" - Global Definitions / Parameters

I defined the parameters in Global Definitions as below: ... E1 E1_fv_f+E_m(1-v_f) "Lamina Young's modulus 11, from rule of mixture" E1C E1_fv_f+E_m(1-v_f) "Chamis model longitudinal Young's modulus" ...
But only E1 can work in 1D Group Plot in Results. When I plot graph with E1C it failed with the message "Cannot evaluate expression" and the detail as undefined variable E1C.
Could you please tell me how to fix this?
