Undefined variable using evalin

I'm trying to create a function where it returns the Temperature as a function of time from my data structure. I'm not sure where my syntax is wrong but I get an undefined varaible "Cure_Kinetics" or class "Cure_Kinetics.neat". In my Workspace, I already have the structure defined and Cure_Kinetics.neat(1).data(1,2) has a value assigned to that index.
function [ T ] = temp_program( data_file )
% Parameter inputs: i for each individual data file
% Grabs initial starting temp and ramp rate from ith data files
% Parameter outputs: Function for temperature
syms t
t_0 = evalin('base', Cure_Kinetics.neat(data_file).data(1,2));
beta = evalin('base', Cure_Kinetics.neat(data_file).ramp_rate(1,1));
T = (t_0 + t*beta);
end

neat = evalin('base', 'Cure_Kinetics.neat');
t_0 = neat(data_file).data(1,2);
beta = neat(data_file).ramprate(1,1);
syms t
T = t_0 + t * beta;
